Handling Invalid Field Mappings

After opening a form mapping for an existing project, if any of the mapped fields map to a target field that doesn't exist, a warning will be presented providing the option to remove the corresponding mapping.  This can happen if the project is based on a template or the project is re-used with a different target server.

Selecting Yes, removes all invalid field mappings.  Selecting No, opens the form mapping and presents the invalid field mappings in red at the top of the field list like this:

To clear the invalid field mapping(s), select the field(s), then click on the Clear Selected button at the bottom of the field list.

Failure to remove invalid field mappings will result in a failure during migration execution.
