[Geoserver-devel] multi-geometry and rendering

Hi all,

I (still) got a blank png image when using multi-polygon geometries from a
postgresql with posgist (1.0.0 RC5) datastore (Gabriel thought/guessed it was
CollectionIterator from lite1/2 that might be broken) :

@231099 [FIN] org.vfny.geoserver.util.requests.readers.KvpRequestReader -
clean request is
BBOX=-5.37588,41.11496,10.51521,51.10804&STYLES=sr250c,R21,sr250n&FORMAT=image/png&REQUEST=GetMap&LAYERS=map2x0:serie_rouge,map2x0:serie_rouge,map2x0:serie_rouge&WIDTH=200&HEIGHT=200&SRS=EPSG:4326&TRANSPARENT=true

acces to data seems ok :

When using geoserver 1.2.3 with the same, there is no problem at all.

System: Linux, Tomcat 5.5.7, geoserver 1.3.0 beta 2 (svn), java 1.5.0_02

Oh, that makes sense. I remember patching literenderer1, and I
definitely rolled it forward to 2.1.x, but, obviously, it's on 1, and
we've switched to 2. The fixes were pretty minor, if you have time you
can just check the logs on lite1, for a message by me about fixing
multis, and put those changes onto lite2. Make a jira for it, and
attach a patch if you can. If not then hopefully someone can get to it
soon.

best regards,

Chris
