I'm still wrestling with the old chestnut of having a dijit tree (which uses the ItemFileReadStore and ForestStoreModel, the nodes of which are links to xPages containing viewPanels. 

The tree is displayed in a div on the left of the screen and the xPages are displayed on the right.   There were initially no problems, until the tree and the corresponding xPages grew to 40, and now the tree refreshes and doesn't retain it's focus when the nodes are clicked and the xPages are displayed.  I have urlPreventCache="false" on the ItemFileReadStore, and the tree itself never changes, so why does it refresh all the time? 

How can I stop this and just have the urls displayed on the right change?  I thought perhaps if I used a ContentPane to house the results that would help, as I understand that they are similar to iframes (which I know nothing about), but that does not seem to affect the problem at all.

 

Any suggestions would be much appreciated.
