5.5.0 (2006-09-16)

• Added: streaming examples to the xttexamples sample application.
• Added: Hibernate version 3 provider as the main Hibernate provider.
• Added: initial version of Oracle Forms -like hierarchical tree. The control (com.itgp.mvc.view.RTree) is offered as-is in this version and will be officially released and supported in version 6.
• Added: the ability to perform a POST using a custom HTTPConnection that does not extend URLConnection. Call method TransportUtil.setCustomHTTPClient(CustomHTTPClient ) and pass is an implementation of new interface CustomHTTPClient (provide for POST operation for byte array and input stream) .
• Added: The ability to modify headings, widths, etc for a column after the column is added to the popup.
• Added: ability to retrieve auto-incremented keys after an INSERT operation. The new key will be displayed in the form as long as the form is not cleared after save.

The encoding mechanism handles both the control of the depth as well as breadth (properties) to be encoded for transmission. This mechanism is offered as a prototype in this release and will be supported fully in version 6.
• Added: beginner-level method to execute a custom SELECT. The new method is com.itgp.mvc.DPanel.executeSelect. If the select is on one table, locking is fully implemented.
• Added: client and server-side performance logging by toggling the XTTS.XML_Debug property in the XTTS_Init.properties file on the server, and com.itgp.mvc.Utility.setClientPerfLoggerLevel(java.util.logging.Level level) on the client.
• Added: new boolean property emptySameAsNull to RTextField and RTextArea that when set to true makes the controls handle an empty string in the view as a null in the model.
• Fixed: bug that did not allow multiple requests in an envelope to constitute a transaction (regression in 5.3)
• Fixed: eliminated all instances of non-UTF-8 encoding for both development and run-time.
• Fixed: arrays of primitives were not available to visual controls bound to object properties using SimpleHandler when they extended DViewSimple.
• Fixed: Issues in NetBeans when module was installed as Global
• Fixed: Changing the selection in one object-bound visual control should trigger the selection to clear in all other object-bound controls that use this control in their selection path.
• Fixed: when a selpath provider has a consumer that is a complex component, and the end-user selects an empty blank row (furnished by the append row filter) in the selpath provider component, then there is a infinite loop of exceptions thrown.
• Fixed: com.itgp.mvc.DPanel could not handle its own streaming any longer because of an implementation bug.
• Fixed: Relation does not trigger when the visual control is a (visual) table column.
• Fixed: when a cell editor gained focus it auto-selected the entire contents of the the cell. This was contrary to the behavior of the simple components.
• Fixed: com.itgp.mvc.Utility.setAndUpdate and normal lostfocus did not work the same for foreign keys
• Fixed: Could not persist the overlay of a new sub-object over an already existing one.
• Improved: com.itgp.mvc.view.OTable performance was drastically improved by caching the number of rows for successive getRowCount calls.
• Improved: the CurrencyFormatter required you to enter the currency symbol or 3 letter code or they fail validation. They now allow purely numeric values as well.
• Improved: a newly inserted row in a table was not automatically given focus.
• Improved: added internationalizable mnemonics to Save, Clear and Close buttons. The mnemonics are defined in com.itgp.mvc.ClientMessages.properties.

Changes in 5.3

5.3.1 (2006-01-11)

This version fixes several problems affecting documentation and property editing in the IDE. No changes have been made to the runtime APIs.

Fixed / Modified

• Fixed the table of contents for the Custom Controls document.
• Fixed several broken links and missing images in the documentation.
• Relocated some misplaced example package documentation to the appropriate section of the table of contents.
• Removed a duplicate .gif file from XTTCDev.jar.
• Fixed a problem that was making the simple path property editor (for object-data visual components) unreasonably slow.
• Fixed a problem that was affecting the editing of properties of the object-data visual components in the IDE.
• The default main application myapp.client.Main provided in the client projects of workspaces now exits properly.

5.3.0 (2005-10-13)

New / Modified

• Reorganized the XTT demo application and the XTT examples as separate workspaces.
• Improved the ANT build scripts in the XTT workspaces for Eclipse.
• Published XTT visual components source code in the xtt-examples workspace.
• Added Server push functionality. See server push example xtt-examples workspace. Also see Server Push "how to" document under "How to do things in XTT" section of XTT help docs.
• Added streaming to remote method calls. New com.itgp.mvc.RemoteMethod methods are called isStreamed and setStreamed.
• Added the ability to terminate remote method calls. New com.itgp.mvc.RemoteMethod method is called terminate().
• Added File Choosers in Form Wizards > Options > Templates so developers can easily add their new templates.
• Refactored relational formatters in order to separate the database-to-model conversion from the view-to-model conversion as follows:
  1. com.itgp.mvc.DBFormatter no longer extends com.itgp.mvc.RFormatter
  2. Refactored the DBFormatter methods. New methods are:
     • public Object modelToDatabase(Object modelValue);
     • public Object databaseToModel(Object databaseValue);
  3. Changed com.itgp.mvc.RMetaColumn methods to set and get DBFormatters, not RFormatters
  4. DBFormatters are copied from the visual control to the RMetaColumn to be used during parsing and saves.
  5. RFormatters in XTT refactored so that only the necessary ones implement DBFormatter
• Enhanced implementation for XttsUtil.getServerCacheFactory() to look in XTTS_Init.proerties for the default name of the ServerCacheFactory implementation. Added the following properties to configuration file XTTS_Init.properties (with examples):

  	#Maximum number of seconds of inactivity for a server push connection (defaults to 60)
  	XTTS.ServerPush.KeepAliveIntervalSeconds=60
  	#ServerCacheFactory implementation class full name
  	XTTS.ServerCacheFactory=com.itgp.server.replication.LocalServerCacheFactory
  

  These properties are stored in XttsUtil and the corresponding methods are:

  	public static int getServerPushKeepAliveIntervalSeconds()
  	public static void setServerPushKeepAliveIntervalSeconds(int aServerPushKeepAliveIntervalSeconds)
  	public static ServerCacheFactory getServerCacheFactory()
  	public static void setServerCacheFactory(ServerCacheFactory aServerCacheFactory)
  

• Max. character width enforcement now added by default to the visual components of GUI forms generated by Form Wizard. Components handling date and number data types are ignored.
• Add new getLastAccessTime() method to com.itgp.server.ClientComm. This method will always return the timestamp (as a long) for last time this ClientComm instance was used. If the instance was never used it will return Long.MIN_VALUE.
• Made ClientComm interface observable by adding the appropriate methods and supporting classes. In com.itgp.server.ClientComm:

      public void addClientCommListener(ClientCommListener listener);
      public void removeClientCommListener(ClientCommListener listener);
  

  Also added class com.itgp.server.ClientCommListener and class com.itgp.server.ClientCommEvent.
• Utility.getHttpSessionID() is superceded by public static String getSessionID() method.
• Minor reorganizing of the Developer Guide and the Javadoc. Added informative comments to the application.properties file in the workspace client projects.

Fixed

• Fixed problem involving threads keeping the axis.jar locked in Eclipse plugin bundled Tomcat, even when web app was undeployed.
• Fixed possible infinite loop caused by com.itgp.server.provider.sql.ConnectionPool when an exception is thrown, and the trace() methods are invoked.
• Fixed problem loading classes from different jars on some application servers (caused by using the system classloader instead of the current classloader on the thread).
• Fixed unnecessary calls to XTTS from object based GUI forms during panel refreshes.
• Super class methods can now be called remotely.
• Fixed localization problem affecting com.itgp.mvc.ToNumber.
• Fixed localization problem affecting com.itgp.mvc.RPopup titles.
• Removed log4j-1.2.8.jar from XTTS - Axis/Web Services library in both IDE add-ons. In NetBeans, readded this jar as a patch to the bundled Tomcat 5.5.7 app server. In Eclipse, improved overly verbose Tomcat 5.5.9 application server output in console window.
• Removed unused imports no longer in RTableColumns classes generated by Form Wizard.
• NetBeans-type source code excluded from workspaces for Eclipse, and vice versa.
• ButtonClose triggers a window closing event instead of calling Utility.closeForm. This gives an JInternalFrame a chance to handle that event.
• ParserServerComm no longer muffles IOException when physical network connection is severed, so that the client can be notified. IOException is now re-thrown.
• Fixed problem of Object Popup Wizard hanging when trying to save the popup after exectuting test run.
• Fixed problem of required field warning appearing twice.

Changes in 5.2

5.2.3 (2005-08-26)

• Fixed: In the Development Kit for Eclipse, fixed the new workspace utility and the xtt-demoapp workspace so that the property catalina.dir, in the property file xttbuild.properties, in the web app project, points correctly to the bundled Tomcat:

  catalina.dir=${ant.home}/../com.itgp.eclipse.XTT_5.2.3/tomcat-5.5.9

5.2.2 (2005-08-25)

This version affects only documentation. No changes have been made to the runtime libraries.

• Fixed: Revised docs to reflect that the xml code in connectors.xml is case sensitive.
• Fixed: Revised connectors.xml in the xtt-demoapp workspace to support the security provider example.
• Fixed: Revised docs to reflect that the wizards are intended to be launched from the IDEs.
• Fixed: Corrected several other typos.

5.2.1 (2005-08-22)

This version affects only documentation. No changes have been made to the runtime libraries.

• Fixed: In Eclipse, HSQL must be started before xtt-demoapp is deployed. Setup Guide revised to reflect this.
• Fixed: Problems in the XTT help contents in Eclipse navigation pane for Setup Guide and Developer Guide fixed.

5.2.0 (2005-08-16)

• New: Development Kit for Eclipse 3.1 available. Developer Guide and Setup Guide correspondingly updated.
• New: Workspaces now automatically generate super-compressed "Pack200" .gz versions of the client libraries inside the .war. The "JnlpDownloadServlet" servlet configured in web.xml will serve up these in place of the regular jars to supporting (Java 1.5) Web Start and Java Applet clients. Super-compressed .gz's makes XTT clients super-thin.
• New: Templates refactored for improved IDE visual editor rendering. Templates for both JInternalFrame and JFrame now provided. This will impact projects that use the raw 5.1.0 templates.
• New: XTT Server Library renamed to simplify upgrade path for Licensed Edition users. This will impact 5.1.0 projects. The old XTTS library will need to be removed and the new library added to the web app project.
• New: Methods callServer and callServerStreamed replace deprecated performParse and performStreamedParse in com.itgp.mvc.Utility.
• New: Methods for sending binary data from client to server added added to com.itgp.mvc.Utility. See example in xtt-demoapp.
• Fixed: "(Re)deploy" now always rebuilds and redeploys the whole workspace to the servlet container.
• Fixed: Problem inserting new object into an object persistence layer fixed.
• Fixed: Problem with OPopup in Web Start fixed.
• Fixed: Numerous deprecation warnings and other warnings in the sample code removed. Some remain for the time being, mostly due use of Axis 1.1. This will be fixed in a future release.
• Many other minor tweaks and improvements.

Changes in 5.1

5.1.0 (2005-06-24)

• New: "XTT project workspace"-based Development Kit created, including a sample workspace, and a utility to create new workspace.
• New: All documentation and java docs now consolidated under JavaHelp in the IDE. Consolidated docs are browsable and searchable.
• New: UniClient product merged into XTT. UniClient provider is now included in the XTT Server .jar .
• Fixed: New popup methods added to give popup a "parent" window. Popup code template updated correspondingly. This prevents popups from going behind the forms that launch them.
• Fixed: Certain messages no longer go behind Wizards.
• Many other minor tweaks and improvements.

Changes in 5.0

5.0.0 (2005-04-07)

This new version offers a long list of new functionality:

• Direct integration with persistence layers, specifically JDO (Java Data Objects) and Hibernate. This allows for the remoting of objects from the persistence layers to the remote client and automatic updates/inserts/deletes of the remote objects back in the persistence layers.
• The ability to remote Java objects (not just serializable ones) in a transparent fashion, regardless of whether the object is obtained from the server through a remote method call, call to a persistence layer, web service, etc.
• The ability for the client to load classes on demand therefore reducing the client deployment footprint. The smallest client deployment size (through the Java plug-in in a browser or through Java WebStart) is now 10kB. Just as important is the ability to customize the amount of classes that are deployed on the client from the onset by varying the amount of classes from the 10kB minimum mentioned as a minimum, to deploying all the client classes from the start, to anything in between. For example deploy 20% of the client classes that are always used (menu, logins, main window, etc.), and let the other less used classes be loaded as needed.
• Client data-enabled visual controls that work with Java objects directly. In cases of POJOs (Plain old Java objects - well defined Java Beans) the developer can simply link the visual control to the property path in an object. For non-bean objects, access can be programatically defined for "getting" and "setting" the value from the visual control into the object.
• The client automatically detects and tracks changes to objects using a client-based data model with which data objects are automatically registered and provides the developer with automatic synchronization of changes (in case of persistence layers) or with a list of updates/inserts/deletes that the developer can use in order to decide on appropriated web service calls, remote method calls, etc.
• When working with data objects that contain multiple levels of nested sub-objects, the data-enabled visual controls allow for a point-and-click development-time definition of the selection path for getting indexes needed to traverse the object graph. (For example if the data object is a publisher that contains a list of published titles, in order to edit any title we would probably place a list/tree of titles on the GUI form, and as we select one of them have textfields fill in with the author's name, title of the book etc. The index of the title sub-object within the main publisher object is needed, and can simply be defined at development time by instructing the textfields to obtain that index from the selection in the list/tree.)
• Allows for creation of new data-enabled visual controls based on any 3rd party or custom Java bean that the developer chooses. (For example data enabling a 3rd party custom calendar control that you find on the web or from an existing commercial library).
• The ability to work directly with Intersystems Cache database.
• New wizards for creating direct Java-bean object based forms and popups.
