New Revision: 7608

Modified:
   trunk/MgDev/Desktop/MgDesktop/Services/Feature/Commands/DescribeSchema.cpp
Log:
mg-desktop: Having multiple extended feature classes of the same name will trip up bulk identity property loading of a MgMapBase-derived class. Although technically this shouldn't happen (as extended class names should be unique and authoring tools should be guarding against this), this submission adds a safeguard against this by bailing out of the extension loop once identity properties have been found, preventing subsequent classes of the same name (that shouldn't happen) from triggering MgDuplicateObjectExceptions if found when the loop is continued.
