Sorry about the blank post...

I understand how to create a document object and attach it to a
tex field and then wire in the listeners for edit events.

How do I do the same thing for a dbText field?  When I hook it
up the same way, none of the Update events get called.

Basically I want to update another field based on the data being
entered.

Thanks

Since the dbTextField has a default document,
just get it (it's a method on JTextField, if
I'm not mistaken) and register your event handler.

(You shouldn't need to create and "attach"
a document in either case you describe above.
You would only need to do so if you were
setting a custom document object into the
text field.)

Thanks.  I'll give it a shot.  I orginally went with the
LostFocus event, but I'd rather do something keystroke by
keystroke.
