Problem with GridBagLayout
I used gridbaglayout in a project i'm writing.Usually, it's suppose to take any number of specified rows or columns but whenever the components are more than 7,it throws a null pointer exception with the following error msgs : java.lang.NullPointerException

Is it a peculiar problem with the sdk 1.5 and how do i solve this.

No - there have been numerous reports of GridbagLayout being able to
successfully cope with 7 or more components.
Sorry. But a Java bug is the very last thing to consider.

You really need to post a small example tha compiles and shows this
problem when it's run. You will, almost certainly, have to construct this
example, as your existing code will be rather long. In the course of
constructing such an example you may well solve the problem, so it's not
wasted labour.
You should consider posting in the Swing or AWT forums (as appropriate)
as you will get better help there. If you do so, leave a note here saying so.
(My guess is that you're adding a null component.)
