Hello,
I have a map with a base-layer and several overlays. One of them is a
routing-layer which displays a routing graph after calculation. Beside
this I'm using a WMS GetFeatureInfo to query attributes of a WMS-layer
from GeoServer.
The GetFeatureInfo works fine as long as the routing graph isn't
displayed. After calculation the route I always get the answer
"OpenLayers.Util.getElement("nodeList") is null" when I try to query the
WMS-Layer.
I thought that I have to set the layer index of the WMS-Layer higher or
to raise the layer to keep it queryable. But this doesn't help.
Has anyone an idea how to solve this problem?
Thanks a lot,
Astrid
