Is it possible to disable f:event type="preRenderView" listener on postback?
That's not possible with <f:event>. You need to manually check FacesContext#isPostback() inside the listener method.
public void init() {
if (!FacesContext.getCurrentInstance().isPostback()) {
// ...
}
}
In the upcoming JSF 2.2 <f:viewAction> tag, which is supposed to replace this <f:event type="preRenderView"> "workaround", it will however be possible with the onPostback attribute:
<f:viewAction action="#{defaultNewQuestionHandler.init}" onPostback="false" />
Snapshot releases of JSF 2.2 are already available.
