--- Comment #1 from Ralf Habacker <ralf.habac...@freenet.de> --- Today I got the same error with a component diagram. After selecting the first widget clicking on the second widget do not connect both widgets. In a debug session it turned out that in the error case UMLScene::widgetAt(m_pMouseEvent->scenePos()) did not return the second widget in void ToolBarState::setCurrentElement() { ... // Check widgets. UMLWidget *widget = m_pUMLScene->widgetAt(m_pMouseEvent->scenePos()); if (widget) { setCurrentWidget(widget); return; } } -- You are receiving this mail because: You are watching all bug changes.
