[OpenLayers-Users] Add Feature and Pan into View

[Alexandre Dube]

Hi,

You could register a "beforefeatureselected" event on your vector layer 
and set the map extent according to the feature's extent. I think that 
if you use the BBOX strategy, since the feature was already drawn it 
should remain the same when the map automatically pan/zoom to the 
feature's extent.

What do you think ?
