Need help, XCOS superblock Mask Customization Error

[gurunath]

Hi 

I am trying to create a XCos superblock. I have put few blocks of code as a
superblock and created a mask. After that when I am trying to customize it
to give parameters so that I can use the block several times.

I am getting following error when I click Superblock Mask customize


 Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

I looked at several error reports but I didn't find solution.
