Comment 1 Peter Lam 2007-03-20 23:12:24 UTC
low use case not currently impacting our installed user base.
Comment 2 Alexandr Scherbatiy 2007-04-04 13:33:46 UTC
The issue affects Advanced UML Modeling with NetBeans HOL.
I need to put two Use Case elements on the package.
The information dialog taht says 'An element with this name already exists
in the current namespace' appears.
Comment 3 Yang Su 2007-04-09 20:43:32 UTC
Historically, the newly created NamedElement is given a name "Unnamed", which is
also an editable option in Options -> UML -> New Project -> Default Element
Name. There is no other attribute to tell the unnamed from named. The obvious
fallacy is that when default name is modified all previously unnamed become
regular named elements, which causes error in logic where unnamed should be
singled out, like code generation.

The safest approach to address this issue is to ignore unnamed element naming
conflict check and make this option hidden (remove from option list) so users
won't be able to modify it, the distinct name can then be used to mark the
unnamed status. This option was really unnecessary, it did not offer any
benefits. A useful model should be clear and unambiguous, default name only
provides convenience for initial creation and is expected to be changed later. I
don't see such an option in other applications.

Made changes in config file to remove it from option list, and add logic to skip
validation if element is unnamed.
