bad behavior than calling dtkWidgetsMenuBar::touch() inside a widget callback (typically triggered by a dtkCoreParameter::connect callback)
Then calling dtkWidgetsMenuBar::touch() inside a dtkWidgetsCoreParameter* callback, some other callbacks (not connected to the menuItem which has been clicked by the user) may ba called,
This can be tested with the menubar_touch_int and menubar_touch_bool buttons added in exp/dtkWidgetsMenu example. Or in precis application (Generate a fluid triggers the "Solid" file browser)
