Rivendellaudio/web/rdxport/carts.cpp
Fred Gleason bec5067090 2017-06-28 Fred Gleason <fredg@paravelsystems.com> 
* Fixed a bug in 'web/rdxport/carts.cpp' and 'web/rdxport/import.cpp'
	that caused the 'EditCart' web API call to return an error when
	attempting to set the Title field to its current value when
	Allow Duplicate Cart Titles was not enabled.
