Thanks for the reply, I am working on if I can give a small example of my code to make you understand better about the problem.
Meanwhile , just need one more help on the following error :
## parent element "0.0" does not exist at /usr/lib/perl/Tk.pm line 250 ###
The background is , I am creating a tree structure of different kinds and combinations in terms of root node and their children. Basically everytime the tree is having different branches and nodes in it. This above error is coming for a particular combination.
Since the tree is very big, right now I cannot give you an example and unable to find where is the goof up happening.
If you just tell me which direction I should think or what should I look for to get rid of this error would be very helpful.
