JSF 2 / primefaces : p:panel not rendered with ajax?

Question

Im not sure if this behaviour is normal or not.
Im hoping that my panel will be rendered only after clicking on a button that triggers an ajax

Answer 1

put your panel with conditional rendering inside another and update it. Like this:

<p:outputPanel id="toUpdate">
  <p:panel id="myPanel" rendered="#{myBean.flag}">
  </p:panel>
<p:outputPanel>

<p:commandButton update="toUpdate"/>

This is a known issue. The element can't be updated if it doesn't exist in DOM.
