[Users] Workaround for google layers not playing nice with treepanel - MORE DIAGNOSIS of the problem

[Phil Scadden]

I have actually made some progress in finding out what is going on but 
still stumped. Here is the nub of the issue as far as I can see.

Eventually, in both the case where using a treepanel or not, a GeoExt 
callback on "afterlayout" results in a
call to OpenLayers Map Render.
In render you have:

         this.div.appendChild(this.viewPortDiv);

In the application without treepanel, this results in the the GMap2 div 
(a child of viewPortDiv) taking on the
same client width and hieght as div. When you bind mappanel to a 
treepanel however, the GMap2 div remains with a client height and width 
of zero. viewPortDiv however does change to fit the parent div.

Now I just dont know enough about DOM to understand what difference I 
should be looking for in viewPortDiv and its children that can allow 
such a thing to happen. At first glance, viewPortDiv and the child GMap2 
div look the same but then there are a lot of properties. Can anyone 
give me some hints please?
