finally it worked using BindingUtils.bindProperty and rewriting some
code related to [Bindable] get/set methods.
It seems that the main error its due to this "kind" of binding:
text="{iMap.map.selectedLayer.label}"
In that case databinding is not handling gracefully the case when iMap
is null. Such kind of error causes a total break of the app.

unusual for an MXML component that subclasses a display component to
not be an IEventDispatcher, so there is something odd about that
situation as well. Can you give us an idea of what the MXML version
looked like?
