OBJECTS_OBJREF_NOT_ASSIGNED_NO error when accessing some links in DOE

Question

Hello Everyone,
        We have setup a Development system for R&D on SAP NW Mobile 7.1 SPS08. I'm able to register mobile devices (Laptop) in DOE but when I'm trying to access few links (like Administration-->Device Administration) I'm getting error "Access using a 'ZERO' object reference is not possible" and an ABAP dump "OBJECTS_OBJREF_NOT_ASSIGNED_NO" is created. Error Details are given below. Can someone help me out in this ?
Error when processing your request
What has happened?
The URL http://abc.xyz.com:8000/sap/bc/webdynpro/sap/sdoe_administration/ was not called due to an error.
Note
The following error text was processed in the system MOB : Access using a 'ZERO' object reference is not possible.
The error occurred on the application server xyz_MOB_00 and in the work process 4 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: RESOLVE_MAPPING of program CL_WDR_CONTEXT_NODE_INFO======CP
Method: MAP of program CL_WDR_CONTEXT_NODE_MAP=======CP
Method: IF_WD_CONTEXT_NODE~IS_ALIVE of program CL_WDR_CONTEXT_NODE_MAP=======CP
Method: IS_NODE_VALID of program CL_SALV_WD_CHANGE_LOG=========CP

Method: FREE of program CL_SALV_WD_DATA_CHANGE_LOG====CP
Method: FREE of program CL_SALV_BS_DATA===============CP
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system MOB in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server xyz_MOB_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 4 in transaction ST11 on the application server xyz_MOB_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.
Error code: ICF-IE-http -c: 100 -u: SUSER -l: E -s: MOB -i: xyz_MOB_00 -w: 4 -d: 20090806 -t: 114729 -v: RABAX_STATE -e: OBJECTS_OBJREF_NOT_ASSIGNED_NO
