[OpenLayers-Dev] Deactivate Draw-Control after feature added

[Paul Spencer]

Kevin, I am using the same technique and it works just fine.

The featureAdded callback gets called during  
DrawFeature.drawFeature().  This function does not appear to be in  
your stack trace (nor is toggle()) so that isn't your problem at this  
point.

It looks like you have some other code hanging around that is causing  
you problems - something that is handling the dblclick it looks like.

Cheers

Paul
