I'm a newbie to use GeoServer and SLDs so, sorry in advance if my question
is stupid.
I'm trying to use the Point Stacker rendering transfomation for to cluster
my point layer. I've a POSTGIS point layer with more than 514.000 points
(all the OSM addresses in Italy ....), and so I can't to render them with a
simple "red point" in my map and I can't render them using a clustering in
the browser using Leaflet, OpenLayers, ecc ...
The structure of my POSTGIS layer is the following
field_1 BigDecimal true 0/1 field_2 BigDecimal true 0/1 field_3 BigDecimal
true 0/1 field_4 String true 0/1 geom Point true 0/1
The field I'm interested on is "field_4"
If I try to use a default point symbol to render my layer the visualization
is obviously slow but it works right and I can also to identify my point.
I've tried to use the SLD that I've found here
http://suite.opengeo.org/opengeo-docs/cartography/rt/pointstacker.html for
clustering server side and it's working for mapping my layer as clustered
points.
I shoud add more classes in my SLD style and I'll do it, but at the moment
the issue is that, using cluster, I can't identify points, not when
they'are clustered (I don't want this ....), but when they are rappresented
as single point.
The error is "internal error occurred Property 'count' could not be found
in osm_civici": I haven't that field in my layer but I've seen that is a
"field" used in the SLD style ....
NOTE: I'm using the SLD style found in OpenGeo Suite documentation at
http://suite.opengeo.org/opengeo-docs/cartography/rt/pointstacker.html
"as-is" and probably there is something to change but I don't know what
....
I'm using OpenGeoSuite Version 4.0.2 on Windows 7 (GeoServer 2.4-SNAPSHOT
Git Revision f295d37d70c3b1f0e51942e8b031253e4d75459 Build Date 20-Jan-2014

Thank you very much in advance!
