Hi Syed,
I'm not completely sure about this, but it seems like the source of your
error lies in either the bit of code where you're trying to remove the right
widget from the HorizontalSplitPanel depending on whether the given widget
is in the set of widgets you're checking for or in the getX() methods being
called in the setHTML() method calls on your various link widgets. I'm
surprised that the stack trace doesn't go deeper into your own code to
clearly identify at which line the error is occurring.
As far the the link represented by the HTML widget, the code you've written
shouldn't cause any problems, which is why I'm a little suspicious about the
actual cause of the problem.
Can you trace this deeper?
Hope that helps,
-Sumit Chandel
