TO0101

"The item type ... of the list type ... does not exist."

Summary

• Name: ListItemTypeDoesNotExist
• Code: TO0101
• Category: Model Integrity
• Severity: Error
• Since: 0.4

Each custom list type must specify exactly one type of item it can hold, either a built-in type or a custom type. This type is required for providing the correct windows and controls when modifying record fields of these list types, and for serializing and exporting project data.

Example

The following steps generate this type of error:

1. Create a new custom type.
2. Create a new custom list type using that custom type as item type.
3. Delete the custom type.

How To Fix

Either

• change the item type of the list to an existing type, or
• create a custom type with the name of the type referenced by the list.
