Hi Mansour,
I agree that the message is messed up a bit... This particular message is
used in a few different locations in the code. If you have additional
context about when this is received (call stack, persistent operation,
etc), it would help with identifying the specific usage and get that
cleaned up.
Looking at your example, a couple of things jump out...
1) In your PK class, your getter/setter methods don't match the strId
attribute (get/setMessage?). These names need to follow standard java bean
conventions and need to match up.
2) In your GeoAssociation class... It looks like you want the ability to
setGeo and setStrId, but I don't see those methods defined. You have them
defined (sort of, per my first comment) in your PK class. But, you don't
have them defined in your GeoAssoc class.
That's all I've got at this point.
