I have posted this question before on the general StackOverflow forum: http://stackoverflow.com/questions/16278569/select-features-of-layer-which-is-not-on-top
In short my problem is that I have a baselayer, an overlay layer and a WFS layer in OL. The base and overlay layers are WMS using GWC in GeoServer. I want to select a feature of the WFS layer but KEEP the overlay layer on top.
By binding a selectFeature control to the WFS layer moves the layer on top. Using
I move the overlay layer back. But now I can no longer select a feature of the WFS layer.
Adding the overlayLayer to the SelectFeature control doesn't work because it is a WMS layer.
How can I select a feature on the WFS layer which is not on top? I've tried the GetFeature control, but that requires a roundtrip to the server and I don't want.
I've made an sample of my problem at http://www.smartdakscan.nl/webapps/assen/selectFeature.html
Any help is much appreciated.
