The problem is that in 
bool UMLDragData::decodeClip4(const QMimeData* mimeData, UMLObjectList&
objects,
                          UMLWidgetList& widgets,
                          AssociationWidgetList& associations,
Uml::DiagramType::Enum &dType)

only top level widgets are be patched to get a new localid 

            // Generate a new unique 'local ID' so a second widget for the same
            // UMLObject can be distinguished from the first widget
            widget->setLocalID(
                doc->assignNewID(widget->localID())
            );

but in 
bool MessageWidget::loadFromXMI(QDomElement& qElement)
... 
        QString tag = element.tagName();
        if (tag == QLatin1String("floatingtext") || tag ==
QLatin1String("UML::FloatingTextWidget")) {
            m_pFText = new FloatingTextWidget(m_scene, tr,
operationText(m_scene), m_textId);
            m_scene->addFloatingTextWidget(m_pFText);
            if(! m_pFText->loadFromXMI(element)) {

the related FloatingTextWidget fetches localid from the xml fragement

bool UMLWidget::loadFromXMI(QDomElement & qElement)
{
...
    QString localid = qElement.attribute(QLatin1String("localid"),
QLatin1String("0"));
    if (localid != QLatin1String("0")) {
        m_nLocalID = Uml::ID::fromString(localid);
    }
