Modifying a modal dialog from another dialog

Thread view:

I have a modal dialog with a text area and a button on it. The button
launches another dialog. This second dialog has buttons on it which
attempt to change the text area on the original dialog, however, this
dialog is 'frozen' and none of the buttons work. I know this is an
event/threading issue but I'm not sure of the proper way to design this
task. The first dialog must be modal. I tried launching the second
dialog in a separate thread but that had no effect and I think it
violates the swing thread safety design issue anyway. Any ideas?
Thanks,
Cliff.

What is specified as the parent of the second dialog ?

No parent has been specified. I posted some sample code which
demonstrates this problem and it should appear online shortly.
Thanks,
Cliff.

Make the modal dialog the owner of the sub-dialog. The API docs for Dialog
(from which JDialog is sub-classed) describe this:

"A dialog can be either modeless (the default) or modal. A modal dialog is
one which blocks input to all other toplevel windows in the application,
except for any windows created with the dialog as their owner."

i.e.
subDialog = new JDialog(modalDialog);
