Query Attributes of FeatureCollection gets missing in StreamingRenderer
------------------------------------------------------------------------
Key: GEOT-1861
URL: http://jira.codehaus.org/browse/GEOT-1861
Project: GeoTools
Issue Type: Bug
Components: core render
Affects Versions: 2.5.0
Environment: NetBeans 6.1
Reporter: Theuns Heydenrych
Assignee: Jesse Eichar
The Query Attributes in the StreamingRenderer disappear in the
StreamingRenderer.
When the method queryLayer(...) in the StreamingRenderer executes it gets the
style attributes through the call findStyleAttributes(styles, schema)
which return only the default one namely "the_geom".
Then a new query is created with only this one property with the result that ,
the original properties is not there any more.
With the new dynamic graphics interfaces , you can give a expression in the
location url for the graphic , this url will be evaluated when the icon is
asked from the implementation of the ExternalGraphicFactory. The properties of
the query will bind data to the feature to be rendered , when these properties
are not there the icon can not be given correctly.
Please refer to
http://docs.codehaus.org/display/GEOTOOLS/Dynamic+SLD+Graphic+objects for more
information on the ExternalGraphicFactory.
