Type tree errors

Each card in the map specifies a type and a type tree. Type trees referenced by the map must be analyzed and saved. If you build a map, and a type tree referenced by that map has not been analyzed, or it has been analyzed but produced at least one error, an error message to that effect appears. For example, if the type tree address.mtt was not successfully analyzed and it is used in a map, building that map causes a warning message to be displayed.

You are not prevented from building the map. However, you may get unpredictable results when running the map. For example, if a group's components are not distinguishable, it is not clearly defined where one component ends and the next one begins. The data may not validate correctly.

A type tree that has not been analyzed as error-free includes the following:

• A type tree that was analyzed and produced at least one error.
• A type tree that has been analyzed, but not saved.
