[news.eclipse.modeling.mdt.uml2.uml] UML Interactions via the API

[paul.t.smith@xxxxxxxxx (Paul Smith)]

I'm currently writing some code to interrogate a model that contains an 
Interaction. That interaction has a series of EventOccurrence and Message 
elements. It's basically a sequence diagram and I'm trying to generate 
code from the model that implements the flow of excecution of the sequence 
diagram.

I'm using the following code to get the Messages of the interaction:

List messages = interaction.getMessages();

for (Iterator messageIterator = messages.iterator(); messageIterator
                               .hasNext();) {
   Message message = (Message) messageIterator.next();
   logger.trace("Message name: " + message.getName());
   logger.trace("Message sort: " + message.getMessageSort().getName());

This all works but I cannot seem work out a way of determining the 
sequence of those messages. I tried looking at the GeneralOrderings of the 
EventOccurrence but the lists are always empty. Does anyone have a way of 
doing this?
