Can't change the order in interaction diagrams

[bknoth]

I'm just trying to move a message line up in an interaction diagram so that it preceds some other messages. I drag it up with the mouse, release it, and it jumps back to where it was. I can't change the order of the messages.

What am I missing?

I just downloaded EA 6, and had the problem with version 5 also.


Thanks,

Bruce

I guess you mean a Sequence Diagram?

I'm having exactly the same problem on every EA version.  Has anyone figured this out or know a workaround?

First thing to do is check that the diagram actually is a sequence diagram: double-click on some empty space to bring up the diagram properties dialog and the title of the dialog should start with the words "Interaction Diagram". If it doesn't, you'll have to start again: right-click the package that owns the diagram in the Project View, select the "Add | Add Diagram" command, and then select the "Sequence" radio button on the New Diagram dialog.

Before starting a new diagram from scratch try setting the diagram type to a sequence diagram.

Select Diagram | Change Diagram Type from the Main menu.  You could also use this the check the current diagram type.

Thanks!  Making sure it's a sequence diagram when starting from the beginning does the trick.  It also makes the rest of the diagram much cleaner (i.e. the layout is much more strictly enforced).

I had accidentally created it as a Class diagram, but used all the 'Interaction' objects in the diagram.

Thanks again,

Eric
