How refresh tree without changing structure?

Hello all,

I can't find out how to refresh a tree correctly (the whole tree, from within the java composer class).

I have different icons (traffic light style) in the tree and need to update all of them without changing the structure or display of the tree.

I tried the TreeDataEvents with this code

         wsModel.fireEvent(wsModel.getRoot(),0,0,TreeDataEvent.CONTENTS_CHANGED);

TreeDataEvent.CONTENTS_CHANGED - nothing happens
TreeDataEvent.STRUCTURE_CHANGED - updates the icons, but the tree collapses, selection is lost
TreeDataEvent.INTERVAL_ADDED - first node gets duplicated
TreeDataEvent.INTERVAL_REMOVED - first node disappears

Maybe the problem is the range of the elements that receive the event: with

         wsModel.fireEvent(wsModel.getRoot(),0,7,TreeDataEvent.CONTENTS_CHANGED);

Is there a way to refresh the whole tree, without firing the ON_CLICK Events?

Thanks,
F. Schuster
