looking at the source of the CapabilitiesTransformer near line #1572 i see:
Envelope bbox = null;
bbox = featureType.getLatLonBoundingBox();
start("ows:WGS84BoundingBox");
element("ows:LowerCorner", bbox.getMinX() + " " +
bbox.getMinY());
element("ows:UpperCorner", bbox.getMaxX() + " " +
bbox.getMaxY());
end("ows:WGS84BoundingBox");
1/ any ideas why bbox is sometimes null?
2/ does it make sense to check for null before emitting this element?
TIA + cheers;
