[udig-devel] Default style for generic geometry fails to render from SQL datastore

Wed, 12 Jul 2006 05:57:36 -0700

This bug involves default style for generic geometry in UDIG, but is actually caused by geotools issues. I opened 

http://jira.codehaus.org/browse/GEOT-890
on Geotools JIRA, but I thought I would also post here for possible UDIG test cases or workarounds.
I have a postgis table with generic geometry type. Udig (correctly) sets up style in SLDContent#createGeometrySLD by creating several rules with different symbolizers, one for each geometry type case. But condition parts of these rules somehow leak through StreamingRenderer, resulting in this bounding box filtering condition on datastore:
[[ geometry bbox POLYGON ((5285442.209046828 4969855.4245647825, 5285442.209046828 5343298.0754352175, 5722524.790953172 5343298.0754352175, 5722524.790953172 4969855.4245647825, 5285442.209046828 4969855.4245647825)) ] AND [[[[[[[ geometryType(geometry,) = Point ] OR [ geometryType(geometry,) = MultiPoint ]] OR [ geometryType(geometry,) = LineString ]] OR [ geometryType(geometry,) = LinearRing ]] OR [ geometryType(geometry,) = MultiLineString ]] OR [ geometryType(geometry,) = Polygon ]] OR [ geometryType(geometry,) = MultiPolygon ]]]
Since neither SQLEncoder nor SQLEncoderPostgisGeos knows how to deal with FunctionExpressions, layer rendering is aborted with following stack trace:
