I see that if I set:
featureClass: OpenLayers.Feature.WFS
then the WFS data is shown at all zoom levels. So it doesn't work when I
use my own feature class. Is there something extra I need to do here to
make it work? The initialize function in my feature class isn't called
even though the GML is fetched.
thanks, Andy
