[news.eclipse.modeling.mdt.uml2] Re: Sequence Diagram Messages

[mary***@****.com (mary)]

Hello again, 

I am still facing a problem with the ordering of the messages in an 
interaction. I understood that the order of MOS, specify the order of the 
messages in an interaction diagram. 

Let me give you an example to help me explain my problem:
I have an interaction with 2 lifelines and a sequence of messages between 
them. I am trying to add a new message to the beginning of the 
interaction. 

I tried to do that using the property toBefore of the MOS that takes 
element of type general Ordering, and in the general Ordering element I 
set the property before to the first element of MOS in my interaction. but 
unfortunately this way didn?t work.

I am wondering if you have another idea to do this?

Thanks,
