Hi there,

I am trying to implement a CheckBoxTreeViewer and facing this problem.
On expand of a CheckBoxTreeViewer node, getChildren() method of provided ITreeContentProvider is called only for the first time.After that if you again collapse and expand that node, this method is not getting called again.
I am making some changes to a node so that its chaildren are different now but on expand it is still showing the same children which are no more valid.
What should I do so that viewer again make the use of provided ITreeContentProvider to get the children nodes of that tree node ?

Any ideas?

Try calling refresh() with that node
