How do I model calls made in an iteration?

Using EA 8.

I've previously only created class diagrams in EA.  I'm now working on some sequence diagrams, and there are some simple things I want to model that I can't figure out how to do in EA.

I have a class "Foo" that has a method "do" that calls a method "getit" in another class "Bar". The "getit()" method is called in a loop while iterating through a collection of "Bar" objects.

It's more complicated than this (each loop iteration actually spawns a TaskExecutor task to make the "getit" call), but I think this is enough detail to model.

It's easy enough to add a "getit" message from "Foo" to "Bar", but that's not enough.

I tried a "self-message" and gave it an ad hoc label saying that it's iterating through a list.  However, when I tried to add a "message" from that indented block to "Bar", it just added the new message line BELOW the indented block, making it seem like the new message comes after the iteration is done.

I guess I've figured this out. Examples I found on the web show using a "fragment" with a "loop" label.  I also added another fragment inside that with a "par" label (standard for parallel execution).

Yep, that sounds about right.
