Runtime error when compiling Datavisualization SWC from extracted source (Flex Builder)

Issue

---

The source files delivered with Adobe Flex Builder 3.0 Professional (for example, the DMV files that are extracted when the Professional license key is extracted) do not compile into a runnable SWC unless you first modify the dmv_automation_build.xml file.As a result, creating and running any project containing the Advanced Datagrid component results in a runtime, exception and the application does not load.

This issue has been documented as bug FLEXDMV-1626.

Reason

---

This issue occurs after you enter a valid professional license and then attempt to compile the datavisualization source (ant -f dmv_automation_build.xml). When you create and run any new project using ADG components, the following runtime exception will occur:

TypeError: Error #1007: Instantiation attempted on a non-constructor. at mx.controls::AdvancedDataGridBaseEx/getSeparator()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0\fbpro\projects\datavisualization\src\mx\controls\AdvancedDataGridBaseEx.as:4130] at mx.controls::AdvancedDataGridBaseEx/createHeaderSeparators()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0\fbpro\projects\datavisualization\src\mx\controls\AdvancedDataGridBaseEx.as:4167] at mx.controls::AdvancedDataGrid/createHeaderSeparators()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0 \fbpro\projects\datavisualization\src\mx\controls\AdvancedDataGrid.as:1712] at mx.controls::AdvancedDataGridBaseEx/drawSeparators()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0\fbpro\projects\datavisualization\src\mx\controls\AdvancedDataGridBaseEx.as:4091] at mx.controls::AdvancedDataGridBaseEx/updateDisplayList()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0\fbpro\projects\datavisualization\src\mx\controls\AdvancedDataGridBaseEx.as:1860] at mx.controls::AdvancedDataGrid/updateDisplayList()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0 \fbpro\projects\datavisualization\src\mx\controls\AdvancedDataGrid.as:5924] at mx.controls.listClasses::AdvancedListBase/validateDisplayList()[C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0\fbpro\projects\datavisualization\src\mx\controls\listClasses\AdvancedListBase.as:3071] at mx.managers::LayoutManager/validateDisplayList()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\managers\LayoutManager.as:602] at mx.managers::LayoutManager/doPhasedInstantiation()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\managers\LayoutManager.as:657] at Function/<a href="http://adobe.com/AS3/2006/builtin::apply%28%29">http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\UIComponent.as:8460] at mx.core::UIComponent/callLaterDispatcher()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\UIComponent.as:8403]

Solution

---

Edit the dmv_automation_build.xml configuration file using the steps below.

1. Edit the dmv_automation_build.xml configuration file in the <flex builder install dir>\sdks\3.0.0\fbpro directory and replace the following two entries
   • <include-file name="defaults.css" path="${framework.dir} /defaults.css"/>
   • <include-file name="data_management.css" path="${datavisualization.dir}/data_management.css"/>
   
   with the single line below:
   • <include-file name="defaults.css" path="${datavisualization.dir}/data_management.css"/>
     
2. Save the file and rerun the build as ant -f dmv_automation_build.xml.

This solution will produce a valid SWC and eliminate the runtime error.
