Hi,
I have some data in geoserver and I want to display them. At the end I want
to be able to click on an element and to get some informations about the
clicked feature. So I added a wms-layer. Then I wanted to add a
vector-layer with the same geometry but as vector elements.
My Problem now is that I can't see the vector elements. As you can see in
the following code I added different elements (as WMS buildings and as
vector roads) to see when the vector layer appears. I can see the title of
the vector layer in the layerswitcher but not the layer itself.
So, what did I wrong? Can anybody help me?
