Linking Use Cases in Sparx Enterprise Architect

Question

I am trying to link a Use Case in one diagram to a diagram that will detail this use case.

What I am doing is:

• Create new Use case diagram (Right click on Model -> Add -> Add Diagram)
• Call the diagram "Test"
• In diagram add use case (Right click in diagram - > New Element or Connector -> Use case)
• Call the Use case "Test Link"
• Select "Test Link" and add Use case diagram (Right click on "Link Test" -> Add -> Add Diagram)
• Call the new diagram Test Link Diagram"

What I expected now was to be able to double click on "Test Link" and that would take me to the "Test Link Diagram". What happens is that it opens a property windows.

Does anyone know how I can link a use case to a use case diagram?

Answer 1

Unfortunately, as of 2017 (using Enterprise Architect 12.0), the problem still persists. It seems that, although the

Right Click on Use Case -> New Child Diagram -> Add Diagram

approach adds the desired child diagram, the link is not established. In order to achieve that, one has to go through a second cycle of clicking as follows:

Right Click on Use Case -> New Child Diagram -> Select Composite Diagram

The pop-up window should already have pre-selected the child diagram created in the first step. Click on OK, and you’ll be rewarded with a use case that has the link symbol in the lower right corner. Now a double click will open the child diagram.

Fixed it. The trick was Right Click on the Use case - > Advanced -> Make Composite
