Extending Cartridge Packs and Cartridges by Replacing Stub Rulesets

You can extend a cartridge pack or cartridge by replacing stub rulesets with rulesets you create. Stub rulesets have no default logic associated with them. When you replace a stub, your logic executes at the extension point associated with the ruleset. Stub rulesets typically provide opportunities to extended validation and auto-allocation.

You give your ruleset the same name as the original in the cartridge pack. When you install your cartridge into UIM, your version of the stub ruleset overwrites the stub ruleset installed with the cartridge pack. Because Design Studio requires unique names within a workspace, you must create your ruleset in a workspace that does not include the cartridge pack project with the stub.

Alternatively, instead of having a separate workspace, you can just close the other project that includes the entity with the same name.

See "Working with Rulesets" for more information about working with rulesets.
