[Users] Get Position from Vectorlayer

[Andreas Hocevar]

Hi,

your problem is that there is no e.xy for the featureselected handler.
So instead of

map.getLonLatFromPixel(e.xy);

you will need a reference to your SelectFeature control (e.g.
selectFeature), and do

map.getLonLatFromPixel(selectFeature.handlers.feature.evt.xy);

Andreas.
