i have a TreeView component with its data bound to and XmlDataSource object. According to different users different xml strings are generated and bound to xmldatasource and also to treeview component.

when i first login as one user, treeview is shown correctly and the xml string. but when i close the ie, and start application and login again with another user, different (i see in the test div) xml is generated(normally), but when i bound it to treeview, treeview shows the past xml data(the one which i logged in first)
