Hi
Thanks for the response. Yes, what you say is very true. However, it
doesn't help me. The problem I've got is that I have a method which is
called just before a tab is closed. If the contents of the tab has
been modified, but not saved, I want to pop up a yes/no/cancel box so
that the user can save, not save or cancel the close option. If they
cancel I need to return false from the original method, otherwise
true. I don't think that can be done asychronously:
public boolean doBeforeClose()
{
boolean close = true;
// Show box and reset close.
return close;
}
Thanks
Paul
