Dragging Classes onto Sequence Diagrams

[Wargfang]

Please be gentle if this is a really stoopid question.

I have a set of class models.

I am doing a sequence diagram. I dragged on of my existing classes onto my sequence diagram (I added it as a simple link) and as I expected it got created as a lifeline. I then degined several 'Messages' and 'Calls' that involved my class/lifeline.

None of them appeared on the class as methods.

I thought they would (along with their description and params). Why didnt they ? / shouldnt they ?

They way you do it is when working in conceptual phase. All methods are only existing on the diagram. If you defined a method first inside the class you can select it from the drop down list when creating the message.

If you want to create new operations while working on your sequence diagram, click on the "Operations" button in the Message Properties dialog. Then you can add a new operation and afterwards you can select it from the drop-down list.

Thanks for that.
