Hi, I was not aware, that order of code matters here, but good to know!
I rearranged the code, so that the vectorLayer Sites is added to the map before the grid gets initialized. Now the "sm: new GeoExt.grid.FeatureSelectionModel()" does not break the layout any more, which is great, but the OpenLayersMap now shows a "bluescreen". -> http://www.sfb806db.uni-koeln.de/irtg_webgis/app-sent-to-geoext.html And of course I use firebug, but I did not get that error if I used it on my local files, I just got it if I used it on the uploded version, requesting it via http fromthe server... In the version I uploaded now to the server, I get still the "this.mapObject is null" error, It indicates that it originates from Line 512 in my code, which is: items: [mappanel,tree,legend,descpanel] in the panl = new Ext.Panel() function at the very bottom of the code, where the map object should be initialized as far as I can see? I can't see the problem, can you pleas enlighten me here, on how and in which order I correctly have to initialize the different objects?
