How to let server change view?

I have a container application (CONT APP). This CONT APP is a SDI with 2
views separated by a splitter bar. The left panel is a CTreeView and the
right panel is a CListView. Click on a node (e.g. AA) will activate or
insert the full-server application to the right view. Click on the child
node of the node AA will ask full-server application to switch view.

The problem I have is that the view does not change even though the code was
executed. The same piece of code work on the full server itself.

It is anything I have to do in the container application?

Thanks for any advise.
