Hi,

this problem is highly annoying. I'm dynamically setting panels
contents with this code:


                           if (w instanceof HasWidgets && ui
instanceof HasWidgets){
                                         // clear the elements
                                        HasWidgets target = (HasWidgets)w;
                                        target.clear();

                                        HasWidgets source = (HasWidgets)ui;
                                        Iterator<Widget> itr = 
source.iterator();
                                        while (itr.hasNext()){
                                                target.add((Widget)itr.next());
                                        }
                                }

The exception occurs at target.clear() statement


This works perfectly in Firefox, Chrome, Safari, but Of course IE6/7
is the problem (apparently the screen was still building)..
I noticed that this happens if the clicking fast (so that setting the
panel to another occurs)
results in this behavior.

Is there a workaround for this ? Do I have to change something.

Rockster
