Vista 5.1.6 or older that is upgraded to Vista 5.1.7
Incorrect configuration of TGML graphic.
The TGML editor and engine has been upgraded in Vista 5.1.7 and more checks are in place to detect user errors. There are now checks for both bindings and links without a name.
Ensure that all links and bindings have a name. If a graphic is edited in Vista 5.1.7 a prompt will appear when saving the graphic if a link or binding doesn't have a name.
