I faced a similar problem. I included the source code of tomahawk and debugged it.
I found that the encodeBegin has a method which will restore opened states. Now this method will not be called when the tree is constructed afresh. Check to see if the tree is getting constructed again. In my case I had a panelNavigation2 inside a custom component and therefore it made it easier for me to debug it. I am not sure what is the case with you. > -----Original Message----- > From: Christian Kölle [mailto:[EMAIL PROTECTED] > Sent: Friday, January 26, 2007 2:13 AM > To: users@myfaces.apache.org > Subject: My 1.1.5 <t:panelNavigation2> looses its state. > > Hello, > > Prenotes: > I am not very familiar into the JSF-Myfaces deep-ends.
