SysML: Cannot realize information flows

[Bex]

Hi,

I'm using EA 7.1 with the MDG Technology for SysML 1.0 and I cannot see how to realize an information flow on a connector between flowports on an Internal Block Diagram.

The help indicates that by right-clicking you can select Advanced > Information Flows Realized... but there are no information flows to "realize" in the dialog.

I must be doing something wrong as the SysML example that ships has them but I can't see where I'm going wrong.

Any ideas?

Thanks.
