Java Development Tools

Hi all,

Please help -
I got this exception when try to retrieve a table row from my backing bean:
Caused by: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlHierNodeBinding cannot be cast to oracle.jbo.uicli.binding.JUCtrlValueBindingRef

The line of code in the backing bean caused the error:
oracle.jbo.uicli.binding.JUCtrlValueBindingRef tableRowRef = (oracle.jbo.uicli.binding.JUCtrlValueBindingRef) this.getTable1().getRowData();

What bugs me is that the same code works fine in another page's backing bean (see *1) and I can't find out the difference.
My environment:
I am using JDeveloper 11. The application I am working on was migrated from a JDeveloper 10g app, so the components are mostly Trinidad. We had to do a lot adjustment to get that app to work in 11g. The working page I mentioned above was done in 10g app (*1).
I am now adding more things into this app. The app's setup is EJB session beans and Trinidad components now.
In the jspx page, I have a table which was made up with a view from the database (NOT VO). I have a command link in a column in that table, and would like to get a Id from the row in the table. The line of code causes error above is in the command link's action method.

Please help if you have any clue.
Thanks a lot!
Sophia
