How to instantiate PropertySpecifier for a localFill

Hi,

I'm trying to use the DataManager's localFill method but can't seem to instantiate the PropertySpecifier argument.

Since the propertySpecifier is required, I can't use localFill.

To instantiate a PropertySpecifier you need a ConcreteDataService, mode and extra argument. However, I can't instantiate or get/cast a ConcreteDataService since it's a locked class.

So how does one use the propertySpecifier and by extension the localFille method?

Thx in advance,

David
