切换jsf组件而不支持bean？

Question

How can I use (eg ajax) to show a specific jsf element if I click the button where the ajax tag belongs to? But without having to use any backing bean, just by JSF components without JavaScript? Is that possible?

Answer 1

Luiggi is right , You better use js for client side toggling

But , I think you can bind like this

<h:inputText id="first" binding="#{someViewButNonManagedBeanObject}"`... 

and than

<h:inputText id="second" render="#{no empty someViewButNonManagedBeanObject}"`...

or

<h:inputText id="second" render="#{someViewButNonManagedBeanObject.value eq 'wow'}"`...
