Hi,
I have a self implementation of a rich:tree and i think my implementation is right.
I can display my tree and load children without any problem.
But if I want to perform some tasks on this tree (may be add a new node on a button click, delete a node), I always have a ConcurrentModificationException... I can't understand why.
I must say, to add a new node, I need to open a popup window to enter a new name. The failure occurs just before the new windows is displayed...
If someone has any experience/explanation with such issue, thank you to share with me...
Great thanks...
