Error in JCO Connection in RAR 5.3

Hi Experts,

We have maintained the JCO's in the webdynpro in the content administrator. We have created the Connector in RAR 5.3 giving the same JCO Details.

But we are clicking on the SAP Adapters it is appearing as INACTIVE and on clicking on INACTIVE buttion we are getting the below error message

"com.sap.tc.webdynpro.progmodel.context.ContextException: DataNodeInfo(<unknown>): the controller has already been destroyed"

Does anybody encountered this problem? Please help us in solving this error.

Also is there something with the Report Name. We have just given it as "GRCCC123". Not sure whether this has any impact.

Thanks in Advance,

Ambarish
