Problem with JComboBox: No listener added

[Christian]

Dear Instantiations-Team,

thank you so much for providing this excellent tool. This is really what I was looking for!

I ran into a problem when building a GUI containing a JComboBox which I tried to bind to an enumeration. As binding attribute I used the "selectedIndex". The GUI picks up the right enum value which is given via a bean. However, the opposite direction does not seem to work: The bean is not "informed" about changes in the GUI (i.e. selecting a different value in the combo box).

When trying to debug the code I found that in method org.jdesktop.beansbinding:addPropertyChangeListener a log would be written:

log("addPropertyChangeListener()", "can't add listener");

I guess this causes the problem, but I do not know why the listener could not be added.

I build a small test case demonstrating the problem.

Your help is really highly appreciated.

Christian

While this is not a Swing Designer issue, it looks like your bean does not implement PropertyChangeSupport.
