interaction: start a message from a self message

[tvdberg]

This acctually are two problems.

First, starting a message from a self-message in an interaction diagram is valid UML? For me it is, but I do not know for sure.

Second, if it is valid UML, I do not seem to get it working in EA (version 4.00xxxx, build 725).

What I want to do is:

- Add an instance of class A to the diagram
- Add an instance of class B to the diagram
- Add a self-message for the instance of class A (for example init())
- Start a message from within the self-message to the instance of class B (for example connect())

EA places the created message under the self-message. That would indicate it would be started after the self-message is finished. I want it to start and finish within the self-message.

for example:

void A::tick()
{
   if(this->connection == NULL)
   {
           this->init();
   }

   doSomething();
}

void A::init()
{
   B::connect();
}

static void B::connect()
{
   /* connect to something */
}

If I understand correctly what you mean,
please use 'Call' message instead of normal 'Message'
when you make 'connect()' from A to B.

Hope this helps,

Yes, that did the trick. Thanks
