Hi Andrew, Is the binding attribute set in the <tr:treeTable> tag? If so, and if you do not want to persist state across requests, you should clear this attribute -- especially if the bean in the binding attribute is session scoped. Take a look at this article for more information: http://one-size-doesnt-fit-all.blogspot.com/2007/06/follow-up-programmat ic-adf-faces-tree.html Hope this helps, Todd

Removing the context-pararm has had the desired effect I just cant find any decent documentation around org.apache.myfaces.trinidad.CHANGE_PERSISTENCE.

The selection and the expansion state is part for the component state (SaveState, RestoreState). One possibility is that you use a request scoped bean to bind the selectedRowKeys and disclosedRowKeys attributes via EL.

I guess this has been set for a reason :-) Thanks, Andy -----Original Message----- From: Andrew Richards [mailto:[EMAIL PROTECTED] Sent: 02 October 2007 11:09 To: MyFaces Discussion Subject: [Trinidad] request backed TreeTable Hi, I have a Trinidad TreeTable displaying my hierarchy of selectable data which works fine. The problem I having is that when I user selects a row in the table and then navigates away from the page and the returns to the page, the treeTable selection is persisted and the row is expanded and selected? My backing bean is request scoped, which confuses me? Does anyone know how I can force the TreeTable to return to its original state on every new request? Many thanks, Andy
