General New Features:

• Dynamic Rules Engine that provides endless validation for the Domain Objects
• Cache Manager
• Internationalization support for date and numeric fields
• Jaffa.SessionExplorer component which gives a view of all the user sessions
• Component Garbage Collection for better memory management
• Load testing tool
• The DTDs are now stored locally. This removes the dependence on an external website for DTD validation
• Tests for data security
• Added helper methods to StringHelper, to support the concatenation of code and description fields in JSPs
• Added a voucher utility for generating technical keys
• Upgraded from JAXB-EA to the JAXB-1.0
• Upgraded to the latest version of J2EE(1.3.1), JDOM(b8), Log4J(1.2.8), Struts(1.0.2), HttpUnit(1.5.3)

• Extended database support, we've now tested the persistence layer with Oracle 8i/9i, MS SQL Server 2000, MySQL, and PostgreSQL
• Optimized the SQL generated by the JDBCEngine for handling joins
• The JDBCEngine was enhanced to load database-specific constructs while generating DML
• The UOW was enhanced to perform field and domain object validations
• Added logic to perform validations for mandatory fields during a store operation in the JDBCEngine

• Maintenance Pattern and Application Generator to build a complete CRUD app from a Domain Model
• The DomainCreator pattern was enhanced to 'ignore' specified fields
• The Finder/Lookup patterns were enhanced by caching UP entities while generating the results, so that multiple queries are not performed on the same data instance
• Added the descending sort and default sort capabilities to the Finder and Lookup patterns
• The domain object for a criteria/results field in an ObjectFinder is now optional

Presentation New Features:

• Our widgets have been overhauled to support not only IE v5.5 and 6.0, but now we can support Netscape 7.x, and Mozilla 1.3.x
• The button widget has been totally revamped with CSS support
• Added 2 new attributes to the TextTag - popUp and maxLength
• Test rig for FoldingSection and New CSS Buttons

General Bug Fixes:

• Updated Copyright to reference 'All' instead of 'Aerospace'
• The build scripts have been fixed to execute tasks for WindowsXP
• Fixed the JaffaJAR and JaffaToolsJAR target in the build script to also include DTD files
• Fixed the MessageHelper to not pass null arguments when invoking the MessageResources
• Removed the reference to the deprecated class HttpUtils from URLHelper
• Fixed the build script to have 'debug' and 'deprecation' turned on, when creating the JARs
• Fixed the build scripts to exclude the pesky Windows XP file 'Thumbs.db' from the distributables
• Fixed the Finder component to determine the values displayed in the MaxRecords dropdown in a Finder/Lookup, through a framework property
• Changed CustomException to use the java 1.4 getCause() inner exception
• Added fixes to allow mbean creation in Tomcat 1.4.24

Persistence Bug Fixes:

• Fixed the DataSourceCursor to wrap the call to 'setFetchSize' in a try-catch block, since all drivers do not implement the feature (eg.Postgresql)
• Fixed JdbcSecurityPluginFactory such that an exception will no longer be raised, if the property 'framework.persistence.jdbcengine.security.plugin' is not specified in framework.properties

Patterns Bug Fixes:

• The Finder/Lookup patterns were fixed to bring up related Viewers in a new browser window
• The Finder/Lookup patterns were fixed to bring up a 'confirm' message before deleting a record
• Fixed the ConfigFileUpdate to correctly handle filenames having spaces
• Fixed the Uniface domainmeta tool to allow customization of the 'CaseType' attribute of a field
• Fixed the Uniface domainmeta tool to refer to Field Interface Templates while processing a table
• The JDOMParser was replaced by a new class DomParser, which uses the Java1.4 API for XML parsing, instead of JDOM

Presentation Bug Fixes:

• Eventhandling has been fixed to put the desired FormKey on the request stream, instead of setting the 'CurrentFormKey' property on the UserSession
• Fixed the error handling mechanism in FormBase to be more consistent with Struts
• Fixed the UserGridManager to not raise warnings if the UserGridSettings file is not found
• Fixed the Tags to implement the TryCatchFinally interface, since the JSP spec no longer guarantees the invocation of the release() method
• Fixed the TextTag to replace the EndOfLine characters with the <BR> tag
• Fixed a few UserGrid bugs to make the widget more robust
• The UserGrid was fixed to allow disabling hints
• Fixed the lookup.jsp to correctly handle double-quotes
• Fixed the javascript to include input fields of type 'password' in the logic that traps the key presses, so that auto-enter works for password fields
• Improved error handling in the Tags when the WidgetModel in the formbean is not the correct class for the widget consuming the model. It will now give a sencible message when the exception is thrown
