The editor is designed to work in an environment with thousands of maps and structures. Therefore, it is possible for these structures and maps to change independently from each other. In the event of such changes, it is important that they be gracefully handled and reported.

You can force the synchronization of a map with its structures by right clicking the map in the Repository navigator and clicking "Synchronize with Structures".

Alternatively, whenever you open a map, access its properties, or execute it using the runtime API, the map is automatically validated. Any errors or warnings associated with the validation are displayed.

Any map being edited is also automatically revalidated if one of its structures or parent maps is being edited and changes.

Validating a map compares the current map elements to its input and output structures and to any parent maps.
