Your concrete problem is caused by 2 facts:
- When JSF needs to decode a form submit action or a submitted input value, then it also checks if the component is rendered or not (as safeguard against hacked/tampered requests).
- Request scoped beans are recreated on every HTTP request (an ajax request counts also as one request!).
In your specific case, the rendered
condition has evaluated false
while JSF needs to decode the form submit action and therefore the non-rendered input/command components are never processed.
Putting the bean in view scope should fix it. Below example assumes JSF 2.x.
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
@ManagedBean
@ViewScoped
And below example assumes JSF 2.2+ with CDI:
import javax.inject.Named;
import javax.faces.view.ViewScoped;
@Named
@ViewScoped
Or, if the techncial requirement is to keep the bean in request scope, then carry around the condition behind rendered
attribute in a <o:inputHidden>
. Adjust your snippet to include it in the <h:form>
.
<o:inputHidden value="#{backingTest.flag}" />
