Fragments in sequence diagrams (help)

[Tim Kline]

I'm creating a bunch of sequence diagrams. They contain Fragments (the boxes that surround multiple calls) for loops, alt, opt etc.

The problem is that they move around when I move totally unrelated messages calls or other elements in the sequence diagrams.

Then when I move them back, the stuff that was inside them sometimes moves and sometimes doesn't. So basically anytime I move anything, I them have to do several, or sometimes many other moves to fix the diagram.

It is rendering Sequence Diagrams virtually unusable for me.

Is there any way to stop this behavior?

Does anyone know how EA decides to associate things with fragments? It seems to be more or less random.

Please help. I really need to get these things done and I'm spending all my time moving things around on sequence diagrams instead of designing software!

Thanks,
  Tim

Are you using the latest (or latest but one) build of EA?

I think there was something about this in the release notes for one of the past two builds (829 and 830).

If that's not the solution, report this to Sparx as a bug report. Use the link near the bottom of any forum page.

Thanks! That was it.

I was on 7.1 build 828. Upgrading to build 830 seems to have fixed the issue or at least made drastic improvements.

Thanks,

It's also worth trying to hold Alt when moving messages.  This allows you to move a message without moving anything else.  (If I remember correctly.)
