Problem in calling UpdataAllViews()

I''m writing a program in Doc View architecture. I have three views: ListView, RichEdit View and TreeView (no Form Views). Using splitter I have splitted and shown the three views. Now the problem is when I call UpdateAllViews() from TreeViews it is working fine. When I call UpdateAllViews() from RichEditView it is throwing Debug assertion failure.

I have called UpdateAllViews() in Treeviews, when an item is cilcked and when I call UpdateAllViews() when I click the RichEditView, Debug assertion Failed is coming.

How to solve this problem. Please help me in this regard.

Thanks in advance for all.
