[Users] "GeoExt.grid.FeatureSelectionModel()" destroys Layout

[geographika]

Hi,

Do you have FireBug installed for FireFox?
The reason your layout is breaking is due to a JavaScript error:

layer.map is null
at: layer.map.addControl(selectControl);  
http://www.sfb806db.uni-koeln.de/irtg_webgis/libs/GeoExt/lib/GeoExt/widgets/grid/FeatureSelectionModel.js

Your Sites layer has not been added to the map at this point, so the map 
property is null.
Try adding your Sites layer to the map before you create your grid panel 
as in the GeoExt example.

 From the API documentation - 
http://www.geoext.org/lib/GeoExt/widgets/grid/FeatureSelectionModel.html

layer
    OpenLayers.Layer.Vector The vector layer used for the creation of
    the select feature control, it must already be added to the map. If
    not provided, the layer bound to the grid's store, if any, will be used.


Regards,


Seth
