Version: 1.4.1 (using KDE 3.4.1, Kubuntu Package 4:3.4.1-0ubuntu0hoary1 ()) Compiler: gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2) OS: Linux (i686) release 2.6.10-5-686 The pop-up menu on class associations have several commands that allows one to change name, role names and cardinalitity of the association: Change Association Name... Change role A name... Change role B name... Change Multiplicity... If any of these has a string value and you access it using the above menu commands, the OK button gets disabled when you delete all characters from the field. The only way away from the dialog is to press the Cancel button, which keeps the value unchanged. You have to go the Properties command that opens the full Association Properties window to remove any unwanted values. This might a feature rather than a bug but I can not see any good reasons for not allowing the removal of values using this shortcut.
SVN commit 471130 by okellogg: Permit an empty string when changing the name of an AssociationWidget's FloatingText. Strangely, AssociationWidget::slotMenuSelection() is not involved in this - only FloatingText::slotMenuSelection(mt_Rename).
