Can’t display hidden label for Constraint

[Paolo F Cantoni]

We're naming our UML Constraints - so we can tell one from the other.  This will produce a Label.  However, once the label is suppressed (either intentionally or otherwise) there is no mechanism to recover it and make it visible again.

Constraints don't display a name (in a separate label or otherwise)

Tell that to my repository.  I can even (and have) coloured them up.

I haven't figured out how to get it to show, but it does (under, as yet, undetermined circumstances)  ...

Even if constraints notionally don't (currently) display their name if assigned, they should!

In OCL (AFAIK) constraints do have a name. More and more people seem to use OCL. So it would be a good way to add OCL constraints using the name attribute. Just a thought.

Thanks, qwerty,

I thought of that but two reasons why not.

• Narrative Constraints are, typically, MUCH longer than names.  Anyway, names are identifiers, constraints are descriptive.  There's a semantic mismatch.
• This bug means I can't display it when I need to and not when I don't.

BTW: I've had a think about why the (name) label is sometimes visible, but I don't have time to follow it up at present.

You could stereotype your notes and apply a shape script.

Code: [Select]

shape main {
DrawNativeShape();
print("#name#");
}

If you set Rectangular Notation (in this case via script) the note displays, if not in Rectangular, it doesn't.  So now I can show/hide it at will, so to speak (since my shapescript - and it is a stereotyped Constraint - makes no distinction between Rectangular and Non-Rectangular).
