GeoServer

Let's add this thread as well:

Upping priority to critical (thought I still don't have time to work on it).

I believe I can reproduce this on trunk, using release configuration:

1) Remove archsites as featuretype and datastore
2) Delete .prj file
3) Add datastore and featuretype, force to correct SRS ( EPSG:26713 )

Preview, in native projection works fine.

Use reflector to get 4326
http://localhost:8080/geoserver/wms/reflect?layers=sf:bugsites&format=application/openlayers
results in blank PNG and the following traceback:

Hmm... people, are you all using point symbolizers maybe?

I am using the default point SLD, so yes, that's a point symbolizer, but it does have size 6.

So in my case this only appears to happen when I view the layer after adding it. If I restart GeoServer the reflector returns images with data, as expected.

Which makes this a configuration issue?

ps. updated and recompiled latest from both GT and GS 20 minutes ago

Fixed on 1.6.x and trunk. People, from tomorrow onwards (but not today) the nightlies at http://gridlock.openplans.org/geoserver/1.6.x/ should contain this fix. Please download them (along with the datastore extensions you might need) and try it out.
