Thanks for your quick reponse. I have tried it. It didn't work for me. It should. I must have done something wrong. For example,public MyBean { private boolean rendered = true; public void setRendered(boolean r) { ...} public boolean getRendered() {} public void selectionChanged (ValueChangeEvent event) { setRendered (false); } } then I did <h:inputText id="one" value= "abcdefg" rendered="#{myBean.rendered }"/> When the <h:selectOneMenu ../> changes the value, I have set the render to be false. But it is always showing. I would like it to not showing when change the selection. Anything wrong?
The rendered attribute and ValueChangeEvent only come into play when the form is submitted - they operate entirely on the server.
