[OpenLayers-Users] ModifyFeature controls on multiple layers

[Andreas Hocevar]

Hey,

what you're describing here (with the select-feature-multilayer
example) also does not work in OpenLayers 2.12. The clean way to
achieve what you want is to configure a SelectFeature control with an
array of layers. Then you register a featureselected handler for each
of these layers, and in the handler you create and activate a
ModifyFeature control with the standalone option set to true. Then you
call selectFeature on the ModifyFeature control, and editing will work
as expected. In a featureunselected handler for each layer you
deactivate and destroy the ModifyFeature control.

Andreas.
