What I expect - If there is only one transition, it is allowed to have no name. Completed can be returned as the *only* possible outcome then. - If there are more transitions, all with names, completed is not there (why should it? To give the user the explicit option to choose the 'default' transition which he probably does not know which one it is?) - Ending a task with 'null' or nothing makes it take the default transition - If there is more then one transition, none are allowed to have no name (throw an error when parsing) Even better (but that was in the previous discussion) I think a name on a transition should be required. So this ' completed' is not needed then and passing (null) or () makes it take the default transition. Much more clear to me.
