Create UseCase type connector in java

[Jim]

I'm trying to create a connector in java of type "UseCase". My program crashes if I try to do this, but works if i create one of type "Association".

According to the User Guide "UseCase" is a valid type and if i dump my package to console the connectors I created in Enterprise Architect are of type "UseCase".

Heres my code:
                             connector = (org.sparx.Connector) connectors.AddNew("", "Usecase");
                              connector.SetClientID(ucElement.GetElementID());
                              connector.SetSupplierID(element.GetElementID());
                              connector.SetDiagramID(diagram.GetDiagramID());
                              connector.Update();
It will crash when trying to run the connector.Update() so I don't get any error info from the GetLastError

Any ideas?

Cheers.

I think it's case-sensitive... (no pun intended)

Opps, yeah I originally had:
connector = (org.sparx.Connector) connectors.AddNew("", "UseCase");

but I changed it to "Usecase" just to check if it needed a lower case C. Still crashes "UseCase".

Which "connectors" collection are you trying to add to? You should call AddNew() on the client element's connectors collection, then set the supplier id as before.

[Jim]

The "connectors" I had was a collection of all the connectors in the package. I just changed it to be the client elements collection and it is still crashing.  :(

I'm running out of ideas and I don't know java. If you send in a support request and attach the failing code then someone will have a look at it. The support request form is here.

[Jim]

Will do. Thanks for your help.

Hi Jim,

Yes, it should be case sensitive...

What about the following:

Have you tried this with a non-blank name for the connector?

Have you tried the code without the DiagramID line?
