--- Comment #2 from Ralf Habacker <ralf.habacker at freenet.de> ---
After looking into this stuff i found out that there is a problem with the
create-auto-associations logic. 

In bool UMLAttributeDialog::apply() a rename of an attribute type (the
referenced class) is applied to the model and widgets. m_pAttribute->setName,
setType and other methods  emits the UMLObject::modified() signal, which is
connected to UMLWidget::updateWidget(), which itself calls
UMLScene::createAutoAssociations(). 

createAutoAssociations() add's an AssociationWidget instance for each class
attribute, if the related class widget is displayed. Unfortunally it do not
remove outdated associations, which should happens before.
