Hello Fabian,
yes you are right: The error occurs, because in the
this.textField26.addListener I affected another Listener, which tries to
change the content of a selectbox, which is changed in the listener of
textField26.
Is there a possibilty to check the status of a selectbox in a handler?
I think it has todo with hasState().
Kind Regards
Thomas
