You need to enable the button by JSF, not by JavaScript/HTML DOM. During processing of the form submit, JSF will verify in the server side view state as well if the button is enabled or not, as part of safeguard against tampered requests.
E.g.
<p:commandButton id="btnAJAX" value="AJAX" action="#{bean.someAction}" disabled="#{!bean.enabled}" />
<p:commandButton id="btnEnabler" value="Enable" action="#{bean.enableButton}" process="@this" update="btnAJAX" />
with
private boolean enabled;
public void enableButton() {
enabled = true;
}
public boolean isEnabled() {
return enabled;
}
Make sure that the bean is at least @ViewScoped
and not @RequestScoped
, otherwise the action of button will still fail because the bean is recreated during the form submit request and thus the enabled
property will become the default value, which is false
.
