not sure it is an A11Y issue, but this case is reproducible with shortcut only.
add A11Y

Comment 4 Thuy.d Nguyen 2006-11-16 19:05:52 UTC

Link creation via keyboard has been implemented (and still under development for
some special links like those in sequence diagram).  This exception no longer
occurs. Closing the bug as Fixed.

Comment 5 Andrew Korostelev 2006-11-17 14:19:52 UTC

issue is still reproducible.
summary was modified to be more clear:
Problem occurs when user selects link on diagram and invokes Ctrl+Enter.
Not in palette.

Comment 6 Peter Lam 2006-11-21 16:57:54 UTC

workaround: none but exeception doesn't seem like there's harm to functionality

Comment 7 Thuy.d Nguyen 2007-01-13 00:03:34 UTC

This issue is fixed by the fix of another issue (86444).  
Relationship links (e.g. generalization, association, implementation...) are not
supposed to be dragged and dropped from project tree to a diagram or added to a
diagram from the project tree using Ctr-Enter.  A logic has been added to the
code check if the selected element is of type relationship, if so, stop
processing it.

Comment 8 Thuy.d Nguyen 2007-01-16 17:39:05 UTC

Changed status to Fixed.
