store state/expanded nodes of a jtree for restoring state

Question

Hi,

I am working with JTree.
I would like to know what is best the way to know which nodes are expanded in a JTree, so as to save its state (i.e. save all expanded paths).
So that if I call model.reload() the Jtree would not stay collapsed, but I will be able to restore its original state to the user. I.e. all expanded nodes will be expanded.

Thanks
