[OpenLayers-Users] Get WFS features geometry data

[Christine Spietz]

Hi Benjamin,

if I understand right, there are only 2 kinds of features in OpenLayers. 
(OpenLayers.Feature.Vector and OpenLayers.Feature.WFS)

I think "geometry" is only available in OpenLayers.Feature.Vector, but I did 
not really work with the WFS-features.
I made a VectorLayer (OpenLayers.Layer.Vector) and the input of this layer 
is a featureCollection with lots of features. I did not set the 
'featureClass' and so I think I "automatically" got the Vector-Features in 
my Vector-Layer and there is a features variable....

regards

Christine

P.S.: Ja, ich bin die jenige ;-) ...... und habe mich eine Zeit lang mit 
Multiple Feature Selection auseinandergesetzt.
