Johan,

Try using a ITreeContentProvider with your Treeviewer.
ITreeContentProvider#getChildren(Object) will give you the flexibility of
caching your results or always fetching the most current children.

treeviewer.setContentProvider(new ITreeContentProvider() {
// implement interface
});

Hi,

That's not true. When the items are already created the this method is
not called any more. You need to to call treeViewer#refresh(Object).
This will refresh the children from this object.
