Hi,
I found another problem in GetLegendGraphic, when I ask for a legend for a layer with a generic geometry type (GEOMETRY) I have the following exception:
java.lang.IllegalArgumentException: class com.vividsolutions.jts.geom.Geometry is not supported by this method
at org.geotools.data.DataUtilities.defaultValue(DataUtilities.java:997)
at org.geotools.feature.simple.SimpleFeatureBuilder.convert(SimpleFeatureBuilder.java:316)
at org.geotools.feature.simple.SimpleFeatureBuilder.set(SimpleFeatureBuilder.java:297)
at org.geotools.feature.simple.SimpleFeatureBuilder.add(SimpleFeatureBuilder.java:220)
at org.geotools.feature.simple.SimpleFeatureBuilder.template(SimpleFeatureBuilder.java:502)
at org.geoserver.wms.legendgraphic.BufferedImageLegendGraphicBuilder.createSampleFeature(BufferedImageLegendGraphicBuilder.java:534
To solve that I’d follow the following approach:
- for each Rule, scan all the Symbolizers to find the one with the greatest “dimension” (Point = 0, Line = 1, Polygon =2, …)
- choose a Geometry type to match the max dimension found at the previous step and create a sample for that geometry type
- draw the icon as usual for the sample
Obviously this would be done only if I have a generic GEOMETRY, for all the other types the rendering process would be unchanged.
Can I proceed to craft a patch for master to solve this issue?
Thanks.
