Yes, we have two rules. Therefore we thought the renderer will first
draw a layer of polygons, then the layer of symbols and finaly merge
them. But it seems the renderer processes all rules for each feature.
I sent you a private email for the data so you can reproduce the bug.
Thanks a lot for having a look,
Olivier.

Dear Geotools addicts,
in the context of a project dedicated to web thematic mapping
(http://geosysin.iict.ch/trac/wiki/GOWS), we are leading some
experimentations with SLD. One of these concerns the
configuration of a
SLD for the creation of a thematic map with proportionnal
circles. We
use Geoserver to run our tests (while Geoserver uses Geotools,
therefore
I send this post here).
So, here is the SLD :

There a screenshot of the map result :

We're faced to a common problem of rendering engines when drawing
location-based graphical objects (like circles) upon a map. One
way to
solve this is to force to manage centroids in a separate layer of
points. Another way concerns the rendering engine itself, by
doing the
rendering of all features (yellow polygons in the example), then all
objects (all orange circles) and finaly merging all.
What are your opinions about that ?
This looks like you have found a bug in the renderer. Each rule
should be completely rendered before the next one is started. My
initial though was that you had two symbolizers in one rule which
would give this output but you don't so I'm going for bug.
I'm not sure which renderer geoserver uses so I'm not sure how to
proceed with reporting this, Andrea do you know?
It's using StreamingRenderer. I would be glad to have a look at this,
if you could send me a sample of the data that generates this (by
private mail is ok, I won't divulge it).
Btw, which Geoserver version are you using?
Cheers
Andrea
