[OpenLayers-Users] Difference between WMS and WFS on the same Geoserver Layer

Hmm. That is interesting. I would ask this question on the geoserver 
list as well. The key question is whether the coordinate received from 
WFS is being scaled to the correct location on the tile, (OL issue) or 
whether the layer is being correctly drawn by WMS. (geoserver issue). If 
you can calculate a feature positions in pixel terms from tile origin by 
hand, then you could compare with same pixel location by tracing through 
the OL render with firebug. This would settle whether the problem is.
