VK_BACK_SPACE

I derived a class from JTextField, and overrode it's processKeyEvent.
Everything works fine, until it encounters a backspace. Why isn't
super.processKeyEvent(e) working when it encounters VK_BACK_SPACE?(Intensive
debugging showed that case VK_BACK_SPACE is being handled, only the call to
super.processKeyEvent(e) does not seem to be doing anything when
e.getKeyCode()==VK_BACK_SPACE)

Thanks in advance,
Lem

That would depend largely on your code.

[ You know, ..that thing you did not supply.
But before you go dumping 20Kb of code
on the group, review

Why?

It is quite possible that you don't need to use processKeyEvent, in
which case your 'problem' may go away.

What exactly are you trying to do?
