if you are going to keep the details of your code secret, then I'm going to keep the details of my answer secret.
But seriously, you can't seriously expect anyone to be able to help you based on this skimpy information, can you? A good rule of thumb: try to put as much effort into your post as you'd like someone to put into answering it. Another rule of thumb: try to make it as easy as possible for the volunteers here to help you.
Good luck!
Still posting in the wrong forum as well. You should be searching the Swing forum for solution before posting your question in the Swing forum if you don't find the answer.
I see the question wasn't that important anyway as you still haven't posted your SSCCE showing what your code is like.
You had time to post a useless reply, but not time to post demo code, so I guess you really don't want help.

Stop doing it wrong.

Why waste time guessing? Try it. It doesn't matter whether you specify an owner or not.
The OP has been asked to post demo code which can be done in about 6 lines of code. If the OP is not willing to make and effort, why should we.
Majority of the time if you take 5 minutes to create a SSCCE you will find your silly mistake. Thats why I keep asking for one on such a simple question like this.
