Hi Øystein,
You need to add your location layer to the LayerHandler. You've
added it to the MapBean, which is OK in some simple situations but
not when you are also using a LayerHandler. The LayerHandler tells
the MapBean to replace the layers the MapBean has with the ones that
the LayerHandler knows about. So the MapBean is dropping your
location layer that way.
It's always better to manage the Layers (for ordering, and for
turning them on/off) using the LayerHandler, and let the MapBean
react to the LayerHandler settings.
Hope this helps (and sorry for the delay in getting back to you),
Don
