Text Blocks, Forms, Field Sets, Views, and Content Wizards are retrieved from the ITP/MDK Repository at the moment an ITP Model runs (at runtime). Which ITP/MDK Repository installation is used to retrieve these objects from is configured in ITP/Server on environment level. The RepositoryServer setting contains the host name and the port number of the installation to retrieve the objects from.
Which ITP/MDK Repository project within the configured installation is used is by default retrieved from the model itself. Inside an ITP Model a project name is stored. This is the name of the project the model was created in. The stored project name is used to determine which project contains the referenced runtime objects (Text Blocks, Forms, fields, Views and Field Sets).
ITP/Server environments also contain a setting RepositoryProject. This setting can be used to force runtime objects to be retrieved from a specific ITP/MDK Repository project. If this setting is assigned a value, ITP/Server will attempt to retrieve the runtime objects from that configured project instead of retrieving them from the project stored inside the model. Refer to the ITP/Server Administrator Manual for more information on changing ITP/Server environment settings.
