Show confirmation on Interaction diagrams

[maxbandero]

I'm using an interaction diagram as a sequence diagram to show the flow of data from system to system. I would like to show a receipt or confirmation back to the originating system(actor) that the message was received. At the same time I want to represent that the data is being forwarded to another system.

When I try to show this on the sequence diagram, it breaks up the horizontal box representing the actor.

Is there any way to perform this without the break?


Thanks

Right-click the message immediately before the break and select "Extend Source Activation". I hope that does what you want.
