Weblogic cluster OIM 10g - "Edit workflow" selection does not show anything

Question

Hello,
My setup is OIM 10g (9102 BP15) in WLS cluster.
When i login as a administrator and click on "Resource Management" -> Manage -> chose a resource -> "Resource workflow" (from drop down) -> "Edit workflow" on approval/provisioning flows, a new window pops up. However, it doesn't open any workflow details in the GUI. When i click "Done" (IE Yellow Triangle) on the bottom left corner of the IE window and copy the error details, it is:
=============================================================================

On the other hand, if i click on
"Resource Management" -> Manage -> chose a resource -> "Resource workflow" (from drop down) -> "Configure" (Form Data Flow/Reconciliation Data Flow). I see below errors in the log:

Anyone encountered this before in the clustered setup ?
Thanks,

Answer 1

Hello,
But if you see the trace, it is coming from the OOTB library. Isn't it ? It doesn't indicate if there is any issue in any custom beans.
java.io.NotSerializableException: com.thortech.xl.webclient.workflowutil.ImageGenerator$FieldMoreover, i see this error in the log with case 2: ("configure" data flow). However, it is working and the the UI is showing me the data flow with this error in the log.
My major concern is case 1: ("edit" workflow) which is not showing me anything on the UI ?
Ideally, it should trigger Nexaweb client to populate the workflows in the UI.
*1 interesting observation:*
If i go to "Design console" -> process definition -> "Render workflow",
then it opens the workflow in the default explorer and the url which is opened in the browser is same as the previous case. It is working here as expected. Does this means the problem is with Nexaweb client load in the UI in case 1. How to fix this ?
Please suggest.
Thanks,
