Hi, it seems to me that the state saving mechanism of tree2 is broken:
As I wrote earlier today in another thread, tree2 with client side toggling does collapse completely when a leaf is clicked, if URL rewriting is used to track sessions. Thus I switched to cookies and ran into another problem: When I change the tree structure the application dumps. However, when I delete all cookies on the client side and try again, all works well. It is not straight forward to reproduce this behaviour as it depends on how the tree structure changes. Some changes do not cause the app to dump, others do. Note that I didn't change the tree structure dynamically in the web app; I just changed it in the code and redeployed the application. I would guess -- but I don't know -- that the problem is worse if the tree structure is changed dynamically by the web app itself. What will happen, if more than one tree is present in one web app, or even in one page? What, if framesets are used in addition? Regards Andreas Schenk
