[OpenLayers-Users] GetFeatureInfo multiple layers

[Lehtonen, Mika]

Hi Nina,

I use this to get a particular layer info:

QUERY_LAYERS: map.layers[1].params.LAYERS

I really don't know how to choose all the layers, but maybe someone knows. I don't know what happens if you leave the index off...

cheers,
mika
