Model revisions also list the Content Wizards, Text Blocks, Forms and Views that are used in that ITP Model. This information may become outdated when the search path changes or objects are renamed. The changes may cause other objects to be inserted when the ITP Model is actually executed.
If this information becomes outdated, the model (revision) is marked with the annotation [Dependency info outdated], and a small grey clock is added to its icon. This signifies that the information in the Uses folder possibly is not accurate anymore. Running Compute dependencies on the model or the project will re-establish the usage relationships for the [current], [in development], [accepted], and [published] revisions. Older revisions are not computed anymore as this would take much time and be of limited value.
Changing the search paths invalidates the usage information for the entire project. Renaming a Content Wizard, Text Block, View or Form invalidates the usage information for the models using it, and possibly for models using objects hidden by the renaming.
