hi Alain !

i have one guestion - when i create new layer on my map (ParcelMarker).

ex. add a marker of BUS. and i click on it(market is selectable) i get 
this message.
------
Fatal error: Uncaught exception 'mginvalidpropertytypeexception' in 
Unknown on line 0
------

this is strange, on static layer i have no problem whit this.
