If I remove all layers from a map and add some others, the boundingbox changes. In my case it is set to the maximum (-180;180;-90;90). Why does this happen? And how can I avoid this? My hack is to save the map.getViewportModel().getBounds() Envelope, clear all Layers, add the other ones and then I set the boundingbox with SetViewportBBoxCommand. Since some layers belong to a wms, two requests are send to the server.
If a wms server has an internal error one gets a http 500 response. In this case udig dumps a stacktrace to stderr:
!ENTRY net.refractions.udig.project 2 0 2007-06-08 14:13:23.609

Instead of having this dumped to the log file I woul prefer to catch the exception and handle it by myself (msgbox, ... ).
Is it possible to catch these udig-internal messages or register somewhere to be notified if one is thrown?
