Style with FIDFilter + MapLayer(FeatureSource) make the ShapefileRenderer go
crazy
----------------------------------------------------------------------------------
Key: GEOT-2787
URL: http://jira.codehaus.org/browse/GEOT-2787
Project: GeoTools
Issue Type: Bug
Components: core styling, ext shapefilerender
Affects Versions: 2.6-RC1
Environment: Java 1.6_16, Ubuntu
Reporter: Stefan Alfons Krüger
Assignee: Andrea Aime
Fix For: 2.6.0
Attachments: junitShapefileRendererFIDFilterFeatureSourcebroken.diff
When rendering different bounds of an unchanged MapContext/MapLayer, with the
same unchanged Renderer and the same unchanged Style (which contains a
FidFilter!), different/random/wrong features fulfill the FidFiilter! With every
new bound to rendered, other features fulfill the filter.
What i learned while writing this JUnit test:
It only happens if the DefaultMapLayer has been created with a FeatureSource
(not a FeatureCollection) in combination with ShapefileRenderer. With
StramingRenderer it works.
Also works with ShapefileRenderer, if the MapLayer has been created with a
FeatureCollection. Maybe this already rings a bell where the bug might be?
It happens with lines, points and polygons.
The test can be run interactively or not. As it is a pretty complex test, maybe
we should include it for both Renderers and the alternative ways to create the
MapLayer.
I have no idea how to fix this bug. I hope the JUnit test helps. I am in IRC
and ready for help/testing all day (friday) tomorrow...
One more note: I couldn'd show the bug with lakes.shp, so please
"svn cp ./demo/shapefileviewer/src/main/resources/data/shapefiles/countries.*
./modules/unsupported/shapefile-renderer/src/test/resources/org/geotools/renderer/shape/test-data/"
