linking to existing diagrams

[caus4alrm]

I have an existing activity diagram that I'm trying to reference from a new activity diagram.

In the new diagram I've added a subactivity. And it is this element that I'm trying to force to reference the existing diagram. I've been through the help, and have found where I can create a hypertext link, but that doesn't work well within the flow of an activity diagram.

Thanks,
Mark

I had this same problem and finally realized that you need to create the referring diagram first and then the referred-to diagram.  Here's how I've made it work:

1) Create your highest level (most abstract) activity diagram first

2) Add a Subactivity element

3) Double-click the Subactivity element you just added.  This will create a new, blank diagram for the Subactivity.

4) Add elements to the newly-created diagram

If you've already created the subactivity diagram, you can drag that diagram from the Project View (right side of the application) onto the higher-level diagram.

You can also do steps #1 - 3, above, and the cut and paste the contents of your already-created subactivity diagram to the newly-created one.

This wasn't obvious for me either.  Hope that helps.
