[OpenLayers-Users] vector layer destroyed twice throws error

[Chris Green]

Hi Eric

Thanks for your suggestion but unfortunately it doesn't help - I tried to
destroy the SelectFeature Control (testing if null first) before destroying
the vector layer, but there was no change to the problem - I still get
'zIndex is null' errors each of the even number of times that I call it. 

Is there some other way, for example forcing the zIndex to be some arbitrary
value before destroying the layer? I have been trying to devise something on
those lines but have not found a workable method up to now.


Chris

Layer.destroy() doesn't call getZIndex. What calls getZIndex is the
Feature handler (used in the SelectFeature control). Before destroying
the layer you can try to destroy the SelectFeature control attached to
that layer.
