SwingWorker and invokeAndWait

[Greg Steele]

Hello,
My app needs to update a database and the canvas for some functions.  I've
tried code similiar to that below, but I've had the event dispatch thread
deadlock.  I thought I'd be safe using invokeAndWait within a SwingWorker.
Is this a thread safe operation?

Thanks,
Greg


SwingWorker worker = new SwingWorker(){
        public Object construct(){
                //start database transaction

        canvas.getUpdateManager().getUpdateRunnableQueue().invokeAndWait(new
Runnable(){
                public void run(){
                        //perform some dom updates
                }
                });

                //commit database transaction
      }

        public void finished(){
         update.dispose();
      }
};
worker.start();
