HGrid - OA Framework 11.5.10 - JDeveloper 9.0.3

Question

Hi All,
I am struggling with the implementation of the HGrid UI element in the JDeveloper. I am following the steps in the sample exercise in the Dev guide.
I am not clear with the Ancestor Node and View Link Accessor properties.
Has anybody successfully implemented the HGrid ?
Thanks,
Amit

Answer 1

Hi,
I am not getting any exceptions. I am able to get records for the top level in the hierarchy, in my hgrid. nodeDef1 is set to the view instance and view attribute. The issue is more with the childNode1. I have tried setting the View Link Accessor property to the "Accessor for the source view object" and also "Accessor for the destination view object". In the members of childNode1, I have nodeDef2. I have set the View Instance and View Attribute for this. For childNodeDef2, I have mentioned my Tree region - "HGridHierarchyRN in the guide" as the Ancestor node.
I also fear a possibility of a problem/bug with JDeveloper. In the View Link wizard, View Link Properties section, When I check the checkbox for the "Generate Accessor in View Object for the Source View Object" and then click on "OK" and then open the View Link properties again, I see that the checkbox is unchecked. If I check the checkbox again, and click on "Apply", The area for the Source View Object becomes disabled and the checkbox also becomes unchecked.
I am using JDeveloper from patch 4045639.
Please get back to me, in case the doubt is not clear.
Thanks,
Amit
