I want to save tree state in session between requests. I mean expanded nodes, collapsed nodes, selection. It works fine if I use binding of the component. But there are problems with cluster mode. It should be Serializable. But it is sublass of UIComponent, and there could be problems.
I think, it might be used TreeState class. There are componentState attribute. But TreeState must be Serializable to work in cluster mode.
Could you make the tree state Serializable? Or there is another resolving of this problem&
