Agent Add action fails with nullpointer

[[email protected]]

Hi Everybody,

Well for last two days we are facing a peculiar issue with our OTM setup. We are not able to add new action in any agents. We were able to create agents in last week. Donno what happened now. When you click on Add action button in Agents Action section, nullpointer exception is thrown. The error stack trace is as below. However we found that if Don't persist option is selected in Agent Event Restriction page, on Add action, the page is displayed, however you won't see the normal action to add, but only the don'tpersist actions like Before persist, if, esle, endif etc.

The setup is OTM v5.5 Cu#3.

The stack trace is as below -
Error Process: fieldSpecs from class glog.comm.agent.ActionType
java.lang.NullPointerException

Can anybody point the real cause of this issue. Well I am sure that its a data related or some properties missing the configuration. I would appreciate and thank if anybody can help me out to let me know the reason on this error.

Thanks and regards,
Suresh
