[Users] vector layer from WFS not visible

[Kathrin Babiker]

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?
