When I double clock on an operation and mouseover the text box, I can see that it says
<< stereotype >> name(param1:type1 [multiplicity] = default1, param2, ...): returnType
I cant find where I can add the returnType though, I've created attribute classes to use as objects and They are working awesomely for the paramaters,
but I can't find anywhere to add the returnType, I assumed that it'd be done the same way as the paramaters (right click->add->paramater) but there is no return type there.
I'm on a ClassDiagram.
When I type the return type in the style shown ( : returnType) after the parentheses, the text-box shakes and doesn't let me save it.
