By Steven Davelaar on Mar 16, 2011
Oracle JHeadstart 184.108.40.206 is now available for download (build 220.127.116.11.35).
This release is compatible with JDeveloper 11 releases 18.104.22.168, as well as 22.214.171.124 and 126.96.36.199.
Customers who own a JHeadstart supplement option license can download it from the Consulting Supplement Option portal.
In addition to many small enhancements and bug fixes, the following features have been added to JHeadstart 188.8.131.52:
- Support for Dynamic Tabs: There is a new page template insipred by the dynamic tabs functional pattern. Note that this template and associated managed beans are all included with JHeadstart and can be easily customized. The implementation does not depend on the "Oracle Extended Page Templates" library. Additional JHeadstart-specific features include: automatically marking the current tab dirty, initially displaying one or more tabs, ability to uniquely identify tabs by a tab unique identifier, close tab icon displayed on tab itself. When using the item Display Type "groupLink" there is a new allowable value "New Dynamic Tab" for property Display Linked Group In that can be used when you use the dynamic tabs template. For example, this allows you to have a first "EmployeeSearch" group that searches employees and shows the result in a table, and then clicking a groupLink edit icon for one employee in the table, which opens a new dynamic tab showing the linked "CustomerEdit" group for this specific employee. See section 9.3 "Using Dynamic Tabs when Opening a Menu Item" in the JHeadstart Developer's Guide for more information.
- Support for Function Keys: There is a new application level property Enable Function Keys. When this property is checked, JHeadstart will generate context-sensitive function keys. The list of function keys can be
seen by clicking Ctrl-K. The actual function keys shown in the list depend on the location of the cursor in the page. The default mapping of function keys to ADF actions is inspired by Oracle Forms function key mapping, but can very easily be changed. Function keys for custom buttons can easily be added as well. See section 11.7 "Using Function Keys" in the JHeadstart Developer's Guide for more information.
- Support for Popup Regions: There are two new region container layout styles: Modeless Popup Window and Modal Popup Window. With these layout styles, the content of the region container and its child regions are displayed in a poupup window. If the Depends on Item(s) property is set on the region container, the item context facet of the depends-on-item is used to launch the region container popup. If the depends-on-item is a button item, the popup will be launched when clicking the button. If the Depends on Item(s) property is not set for the popup region conatiner, an additional button with the label set to the region title is generated to launch the popup. See section 5.10.4 "Generating Content in a Popup Window" in the JHeadstart Developer's Guide for more information.
- Support for Dynamic Iterator Bindings: There is a new group property Data collection Expression. In this property you can specify an EL expression that determines at runtime which data collection (view object usage) should be used. This can be useful when reusing the same group taskflow multiple times. For example, the Employees group can be used as a top-level taskflow, and as a group region taskflow under the departments group. Rather then setting up bind variables and a query where clause, this use case can be implemented much easier by dynamically switching the view object usage between a top-level employees view object usage and a nested usage under the departments view object usage. The data collection expression can then refer to a taskflow parameter which specifies the actual view object usage name.
- Support for Custom Toolbar Buttons: There are two new item display types toolbarButton and groupLinkToolbarButton. Items with this display type are generated into the group-level toolbar for form layout, and added to the table toolbar for table layouts
- Control over Label Position: There is a new property Label Alignment for groups and item regions that allows you to specify whether labels (prompts) should be positioned at the left of an item, or above the item.
- Support for Icons: There is a new icon property available at group and item level. At item level, this can be used to generate iconic buttons and group links. At group level, the icon is displayed in the header bar of the group, and in buttons that navigate to the group taskflow
- Support for Online Help: At the application level, there is a new property Online Help Provider. Two new properties Help Text and Instruction Text have been added to the group, region container, group region, item region and item elements. These two new properties are only used when a help provider is set at application level. If a help text is entered a help icon will be displayed at the right of the element title, or in case of an item, at the left of the item prompt. If an instruction text is entered, it will be displayed below the element title, or in case of an item, in a popup when the user clicks in the input component of the item. See section 11.6 "Using Online Help" in the JHeadstart Developer's Guide for more information.
- Deeplinking from External Source Like E-Mail: You can now launch the application with a specific page (region) being displayed by adding "jhsTaskFlowName" as parameter to the request URL.
The value of "jhsTaskFlowName" should be set to a valid group name as defined in the application definition. Any other request parameters will be set as taskflow parameters.
For example the following URL will start the application with the Employees taskflow, displaying employee with employeeid 110:
- Ability to Call Business Method from Button: There is a new item level property Method Call where you can select a method from the list of application module methods that have been added to the client interface.
Using item parameters, you can specify the method arguments. The return value of a method call can easily be displayed in an unbound item using a simple EL expression. See section 6.10.3 "Executing a Button Action" in the JHeadstart Developer's Guide for more information.
- Requery when Entering Task Flow: The group-level combobox property Requery Condition has a new allowable value "When Entering the Task Flow" to ensure the latest data are queried when the user enters a task flow. As before, you can still enter a custom boolean EL expression in this property as well.
- Additional Item Properties: There is a new item property "Additional Properties" where you specify additional properties that are added to the ADF Faces
Component generated for the item. See section 12.4.4 "Adding Custom Properties to a Generated Item" in the JHeadstart Developer's Guide for more information.
- New Custom Properties: You can now specify 5 custom properties against region containers, item regions and group regions.
- Easier Taskflow Customization: Most of the content of the bounded taskflow Velocity template for a top group (groupAdfcConfig.vm) has been refactored into separate templates to make customization of generated bounded taskflows easier and faster. Placeholder (empty) templates to easily add custom managed beans, custom taskflow activities and custom control flow rules have been added as well. See section 12.5 "Customizing Task Flows" in the JHeadstart Developer's Guide for more information.
- Easier File Generation Customization: The fileGenerator.vm now uses logical template names instead of hardcoded template paths to generate files. You can now use the Application Definition Editor to create a custom template for a specific file, just like all other templates. In addition, to prevent generation of a file, you can set the template to default/common/empty.vm, the file generator will no longer create files with empty content. See section 12.6 "Customizing Output of the File Generator" in the JHeadstart Developer's Guide for more information.
- Better Support for ADF Libraries: A new paragraph (2.4) in the JHeadstart Developer's Guide describes JHeadstart-specific steps to take when using ADF Libraries. In addition, it is now possible to "import" JHeadstart service definitions from other projects that are packaged as ADF Library so you can reference JHeadstart groups in other projects in the JHeadstart Application Definition editor of the project that contains the ADF libraries with JHeadstart-generated content. See section 2.4 "Packaging JHeadstart-Generated ViewController Project as ADF Library" in the JHeadstart Developer's Guide for more information.
- Use of ADFLogger: The JHeadstart runtime classes now use the ADFLogger instead of Log4j. The ADFLogger nicely integrates with WebLogic, allowing you to configure log levels dynamically at runtime and monitoring log messages from specific threads. To see all JHeadstart debug messages during development, go to the WebLogic log window in JDeveloper, click on the "Actions" dropdown list and choose "Configure Oracle Diagnostic Logging". Now add a persistent logger with name "oracle.jheadstart" and log level "INFO". You can do this while Weblogic is already running.
