[FIXED] [V0.8.1] Store object serialization broken if ReaderID is set to GUID property
This was working before but is now broken with latest SVN update. I have a store with the readerID set to a GUID property (UserGUID). When I add a record to the grid, it auto sets the record value for that property to be same as the rowID. When I save the store, it tries to assign that rowID integer value to my object's GUID property, causing an error.
