JTree re-build - need to save the expanded / collapsed state of node

Hi All,

I have the following problem:
I'm using the JTree object in my application.
Some of the nodes have dynamic children that are being refreshed from
time to time.
The refresh operation removes all the children from the node and build
them from scratch.
I'm saving the state of all the nodes and sub-nodes (expanded /
collapsed) and when I want to re-build the tree according to the state
using the collapsePath & expandPath methods, the tree doesn't expand
collapse correctly (I can see that it "sends" the correct operation but
the tree is not being updated accordingly.

Did someone have to deal with it?
Is there a better way to do it?

Thanks.

.
