Hi,
I'm using 11.1.2.1.0
I have created a fragment and dragged it inside a bounded taskflow(bdf) and dragged this taskflow as a region on a page. this page is working fine.
now I wanted to call another page from this fragment.
so, created another page and gragged it in another bdf.
in the first page, frament , I used hierarchy viewer.
This is fragment:

when I click on the selected menu item, its throwing this error:

java.lang.IllegalStateException: The expression "#{bindings.ProjectSetWorkBenchTF1.regionModel}" (that was specified for the RegionModel "value" attribute of the region component with id "r1") evaluated to null.
This is typically due to an error in the configuration of the objects referenced by this expression.
If it helps, the expression "#{bindings.ProjectSetWorkBenchTF1}" evaluates to "null".
If it helps, the expression "#{bindings}" evaluates to "controller_fragments_ChartFGPageDef_controller_taskflows_ChartTF_xml_ChartTF". Now using an empty RegionModel instead.

Hi Frank,
thanks for your reply.....
sorry for the late reply.....
now I can able to call another pages.
to display the data in hierarchyviewer, I created 3 vo's and created viewlinks for those.
link between vo1& vo2 is resourceID,
link between vo2 & vo3 is setID, and in VO3 projectID is there. these 3 VO's are querybased vo's.
if only , key attribute property for projectID is unchecked in 3rd VO, then only another page is called when clicking on the menuitem.(button is placed in the 3rd level of the hierarchy viewer)
if keyattribute of the projectID is checked, then I'm getting the same error.
if key attribute is not checked, then in the hierarchy viewer, in the respective level the next nodes are not coming when i click on arrow mark. (not Navigating to the left or right to view the next set of nodes)
any idea y key attribute property is opposing in page calling ?
