Hello,

 

No reply yet. Hopefully this doesn't go in the Spam map.

Does anybody have any idea if this is really a bug and who can fix it?

 

Thanks,

Ron

Hello all,

I think I encountered a bug in StreamingRenderer.paint.

When I add more than 1 Oracle layer to a MapContent then the MapBounds are getting wider and wider during paint.

This is what I found in the logging:

FINE: Setting parameter 1 as MDSYS.SDO_GEOMETRY(2003,90112,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,3),MDSYS.SDO_ORDINATE_ARRAY(255965.3627032967,470887.0878461539,259582.76929670328,472508.78015384614))
FINE: Setting parameter 2 as MDSYS.SDO_GEOMETRY(2003,90112,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,3),MDSYS.SDO_ORDINATE_ARRAY(255945.82424175824,470867.54938461544,259602.30775824175,472528.3186153846))
FINE: Setting parameter 2 as MDSYS.SDO_GEOMETRY(2003,90112,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,3),MDSYS.SDO_ORDINATE_ARRAY(255940.2418241758,470861.96696703305,259607.89017582417,472533.90103296697))

It seems that the rendering buffer is not reset after painting an Oracle layer.

The query for the next Oracle layer uses a (computed from style stroke width) rendering buffer of the previous layer and from itself.

If I have many layers this can effect performance significantly because too much features are selected that are not within the view.

I use GeoTools version 10.0

regards,

Ron
