[OpenLayers-Users] Problem with multiple SelectFeature controls

[Andre Pereira de Matos]

We have implemented another solution for this problem...

We made a control that throws events (click, mouseover, mouseout) for a specific group of features, and we don't mind if the features are in different layers or not.

It just works... If anyone want the code I can share it...

I sent a mail to openlayers dev to contribut with it, and I am still waiting for any replay.

Regards,

 From the responses I'm getting in the "[OpenLayers-Users] Switching
Layers Assigned to a SelectFeature Control" thread and some Googling it
appears that handling multiple vector layers simultaneously in
OpenLayers is not well supported. In fact, it basically won't work. Only
one layer of features can be selectable at a time.

What I'm trying is to create only one SelectFeature control, but then
allow the user to pick which layer they want to be "active". After they
choose, I destroy the current SelectFeature control and replace it with
a new SelectFeature control that uses the new layer. It's not elegant,
but it seems to work.
