--------------------

Thrown Exception:
javax.faces.el.MethodNotFoundException: click: package.myBean.click(javax.faces.event.ActionEvent)

--------------------

Clicking the first button (action) works fine, but clicking the second button (actionListener) results in this exception.
After having caused the Exception once, even clicking the first button (action) does not work any more, until the page is reloaded.

I very much appreciate every idea which could help me get forward on this.
Thanks a lot in advance.
