I have tried to publish a table for feature layer in a PostGIS database to GeoServer 2.2.5. The layer was added and published. However, the layer has got a yellow exclamation mark in the "Enabled?" field in Layers view. It is also missing from the Layer Preview page.
Everything seemed OK during the publishing process. I could also add the table to QGIS and it's shown well. Anything I was doing wrong?
Can anyone give me some hints about it? Thanks!
