[OpenLayers-Users] Feature hover and highlighting

[Alexandre Dube]

Hi Abhi,

  The 'overFeature' function is not really meant to be overwritten.  You 
should register a "featureselected" event instead to call your custom 
function.

  Also, see this example that demonstrate a nice with to "highlight 
only" the hovered feature (see eventListeners property for your function 
called on a specific event) :
http://openlayers.org/dev/examples/highlight-feature.html

Regards,

Alexandre
