[OpenLayers-Users] Different icons for popups

[bzrudi]

Hi,

stupid me. I found the problem. Thanks to your advice that the code 
should work I looked around and found that I just forget to add the 
'attraction' attribute to the 'propertyName' list of my WFS request.

And thanks for your advice with the last comma, hopefully there are no 
more IE quirks to come around once I will test it;-)

Thanks again!
cheers bzrudi
