Hi, it seems that the TransformFeature control has a broken destroy function
or maybe its just me doing something forbidden. When you try to destroy the
control there can be an error in line 565. For me it happens when I do the
following.
- start the map
- start using the TransformFeature control
- deactivate the control and delete everything in the used vector layer (I
do this because I want a clear map after I used any kind of digi control)
- using TransformFeature.destroy() now throws an error, because there is no
geometry in the box left.
shouldn't there be a kind of check if the box has no geometry?
If someone else thinks that is a bug and not me using it the wrong way, I
would create a ticket.
Greetings,
Fabian
I made this patch and it works for me:
