[OpenLayers-Users] Fwd: WMS layer getDataExtent?

Hi Alessandro,

I'm also new to the list, but at least this response will get you some 
more attention ;-)

As stated in the docs, OpenLayers.Layer.getDataExtent() is to be 
implemented by the subclasses of layer.

For layers.WMS this is not the case 
(http://dev.openlayers.org/docs/files/OpenLayers/Layer/WMS-js.html) but 
e.g for Layers.Markers 
(http://dev.openlayers.org/docs/files/OpenLayers/Layer/Markers-js.html#OpenLayers.Layer.Markers.getDataExtent) 
the method is defined.

I hope this helped a little bit, but keep in mind that this email is 
coming from a novice.

See you over at mapstorer...
... Marc
