[mapguide-users] Permanent changes in data - Solved

[Stefan Dalakov]

I solved it. The problem was that MG Studio shows that the ID field is 
of type "Double". In the DBF file (as this is a shp Feature source) the 
ID field is declared as N,11,0
So I substituted *MgDoubleProperty *with* **MgInt32Property* and it 
works now.
