NPE in DimensionHelper when feature store is empty
--------------------------------------------------
Key: GEOS-4864
URL: https://jira.codehaus.org/browse/GEOS-4864
Project: GeoServer
Issue Type: Bug
Components: WMS
Affects Versions: 2.1.2
Reporter: Ian Schneider
Assignee: Andrea Aime
Attachments: fixDimensionHelperNPE.patch
When a feature store is empty, DimensionHelper will throw NPE attemmpting to iterate null TreeSet. This kills capabilities doc.
Attached patch handles null, though it is not obvious the semantics of WMS returning null in the first place.
