Hi Romain, Emanuel,
We're experiencing some problems with the secure label and I just have noticed that the ZRTP secure label and button are accessed directly in the SCCallback in the media bundle.
I think that it would be a good idea to move everything related to the gui part (JLabel, JButton,.., setIcon, setText, setToolTipText, etc.) in the ui bundle and to use additional listeners if needed in order to set the current state of the encryption. The ui bundle should get all information it needs about the encryption through a service and listeners. We're thus keeping the dependence to the swing package only in the ui bundle.
