Hi all,
I'm working on the same problem as Bart Kummel. Another problem, but similar
to the problem of Bart Kummel (it is actually on the same page and with the
same bean) is the following:
I bind my booleancheckbox to a UIXSelectBoolean object in my bean (it is
configured as a backing bean in the xml file).
binding="#{myBean.uixSelectBooleanObject}"
In the action listener coupled to the submit button I try to read this value
but get a Null pointer exception.
public void actionMethod(ActionEvent action){
value = getU*ixSelectBooleanObject*.isSelected();
}
Regards,
Jeroen Weijers
