以下是该版本的Release Note:
Overview
Building on the improvements in Studio 3.5, Studio 4.0 extends and
improves both the utility and usability of several key workflows
including events, data binding, and data services. The following are
areas of major change. Known issues and resolved defects are also
discussed at the end.
- Simpler Welcome Page
- New Update Site
- Tabbed Properties View
- Improved Macro Wizard / Macro Editor
- XPath Expression Builder
- Visual Editor Improvements
- New and Improved Data Workflow Wizards
- Expanded Data View capabilities
- Data Services Wizard Improvements
- XML Editing Improvements including support for CDATA and Comments
- Platform Driven Features
- Usability Enhancements
- Upgraded Components
- Backward Compatibility: importing Studio 2.4, 3.0, and 3.5 projects into Studio 4.0 is supported
This release supports Windows XP and Windows 2000. Nexaweb
Studio is based on Eclipse 3.2.1 - which does not support Windows Vista
- therefore this release does not support Windows Vista.
Welcome Page Changes
- "Take a tour" link added that uses local content to walk the user through the features of Nexaweb
- "Browse
Samples" content added with instructions and the user is then directed
to the Nexaweb Perspective - rather than the Subclipse perspective - to
simplify downloading and running samples.
- Documentation links combined
New Update Site
Nexaweb Studio can now be installed into existing Eclipse-based environments via a new update site (http://dev.nexaweb.com/update). This includes:
- Visual Editor
- Event/Data/DS workflow
- License manager
- Add support (Platform exe and zip from dojoe/xap)
- Open XAL files in any project
For more information see the installation instructions page.
Tabbed Properties View
The properties view has been changed to leverage the tabbed property
view to make access of properties faster and more intuitive.
- Attribute groups now each have a separate tab
- Support for user-defined custom attributes
- Integration with the Data View
- Support for non-ui components (e.g. mco, macro, iterator)
- Performance Improvements
- Improved support of clipboard operations
Macro Wizard and Editor
A rich macro builder has been added that allows creation and
management of complex macros, exposing all macro functionality
available to the user in a clear and usable fashion.
- Support for multiple modifications in a macro
- New workflow for editing an existing macro
- Support for mco:execute and macro:macroCall commands within a macro
- Integration with the XPath Expression builder
XPath Expression Builder
XPath expressions are an important part of building Nexaweb applications especially Macros and Data
- XPath syntax validation
- Content assist
- document browsing - particularly useful with data workflow
- Integration with Data Workflows
- Integration with Macro Wizard
Visual Editor
Further feature enhancements have been made:
- Support for rubber banding
- More consistent handling of complex components and nested components
- Additional stability and performance fixes
- Double-click now opens the manage-events dialog
Data Workflow
Previous data workflow consisted of single dialog interfaces for
configuring the attributes of a data tag. In Studio 4.0 new workflow
has been added that guides the user through common actions and provides
clear paths to connect data and user interface together.
New workflow:
- Create data source
- Create data binding
- Populate Component with Iterator
- Create iterator
- Create formatter
Additionally, these workflows have been linked together, and linked
to other workflow, so that combined with clear descriptions of each
step users should be able to quickly and easily add data to their
application.
Data View
To better support the Data workflows, the data view has been improved to bring its utility on par with the Outline View.
- Properties View Integration
- Context Menu support
- Connection management - connected dataSources will stay connected
- Drag
& drop support - drag an XML file or a JSON file directly into the
Data View DataSources node to launch the data wizard
- Now included in the Nexaweb perspective by default
Event Wizard Workflow
The existing add event workflow has been expanded to include additional operations that were available but not obvious to users.
- System service functions have been exposed in Java and Ajax
- Data objects have been exposed
- Service request objects have been exposed
- Re-use existing functions has been added for both Java and JavaScript
- Construct expressions to use MCOs and Macros defined in other files
Additionally, these are configured on a per Platform basis, allowing
extension of the exposed functionality in future platform releases
without requiring a new version of Studio.
Data Service Workflow
New workflow provides a wizard approach to building service
requests, hooks in with the other data workflow and fixes some existing
issues with building service requests in Studio.
- Automatically copy the WSDL in the WEB-INF/WSDL
- More intuitive workflow
- Ability to temporarily map data sources to a result set
- Inclusion of WSDL Analyzer in the perspective
XML Editing Improvements
- Upgrade to the latest version of Oxygen
- Support for comments
- Support for CDATA
- Full configuration of Nexaweb Schemas for proper validation
- type-ahead XML editing when using Oxygen
Platform Driven Features
Several features once hard coded into a particular version of the Studio have been moved into the Platform:
- Insert / Replace operations within the outline view and visual editor
- Palette
- System service definitions
Usability Enhancements
Some additional enhancements have also been added based on the usability results:
- Improved Project Creation dialog
- SVN included in the default perspective
- Package view included in the default perspective
- Context Menu clean up in VE and Outline View
- JSON visualization added to the data view
Component Upgrades
For the "all in one" installer the following components have been upgraded:
- WTP 1.5.4 to 1.5.5
- DTP 1.5.0 to 1.5.2
- Subclipse 1.2.3 to 1.2.4
- Oxygen 7.1 to 8.2
Backwards Compatibility
- Importing Projects from Studio 2.4, 3.0, and 3.5 is supported
