Hi!

I'm having a strange problem when I try to delete an object from the database. When executing the eo.deleteObject(object) method, the following exception is thrown:

java.lang.NullPointerException

What's happening!? Any ideas? I don't see any reference on google to problems related to _registerClearStateWithUndoManager method...
