I 've created a web map viewer using OpenLayers, ExtJS, GeoExt and GXP. I've added a LayerTree (gxp_layertree) that shows layers from various WMS servers (GeoServers). I've also configured a FeatureManager (gxp_featuremanager) with 'autoLoadFeatures = true' and a FeatureGrid (gxp_featuregrid).
The problem appears when I click on a layer tree node: the FeatureManager doesn't "autoLoadFeatures", it just fires a WFS DescribeLayer request to get the column names for the FeatureGrid. Trying to isolate the problem for a couple of hours by commenting and changing code I've discovered it works perfectly with projection setted to EPSG:4326, but not with EPSG:3857 or 900913.
Do you have any idea about why this is happening or how to solve it?? I need the map projection to be 3857 because I have Google base layers.
Thanks in advance.
