It is.

The feature selection model fails to add its select feature control to
the map, because the vector layer hasn't been added to the map yet (so
layer.map is null). This whole issue comes from the fact that we
differ adding the layers to the map in the map panel.

Indeed. You can try out the patch attached to #396. It should fix your problem.
