The manipulation does not affect the overview window, this is correct. I 
would have to check the code why not, but I assume that the overview is 
"abandoned" after initialisation, in other words, it is not being refreshed.

I believe the administration tool does not have to be altered. Maybe I 
have to explain the background of my previous post: I'm working on web 
map context documents, which store the layers of the client in an XML 
document. When I'm representing both map frames (plus their layer 
settings) in the WMC document, I have no way of finding out the layer 
settings of the overview. The default settings are overwritten by 
changes made to the main map. Example: Assume a WMS is available in both 
overview and the main map. Then hide layers of that WMS via the treeGDE 
module.

Other solutions could be discussed, like

* reload the default settings from the database
* always show all layers of the overview WMS

but both solutions don't seem elegant to me, especially if you imagine 
having 7 maps and 3 overviews in one applications.

I believe when Mapbender had been designed it was not intended to ever 
do sth. with the overview window after its instantiation, so then it 
made perfect sense. Now, we need more.
