composite's method is called before preRenderView

Question

I have a JSF 2 .xhtml page which looks like this:

<h:body>
  <f:event type="preRenderView" listener="#{view.init}" />
  <customComponents:mytable />
</h:body>

And the composite implementation

<composite:implementation>
    <h:form id="tableForm">
      <ui:repeat value="#{view.actions}" var="action">
      <h:outputText value="#{action.start}">
        <f:convertDateTime timeZone="#{view.timeZone}" />
      </h:outputText>
    </h:form>
</composite>

Now when I load the view the composite's #{view.timeZone} is called BEFORE listener={view.init}

I don't get this. I want the init message called before the getter is called. Can you tell me where the mistake is?

preRenderView has to be in f:metadata tag. For example:

<f:metadata>
  <f:event type="preRenderView" listener="#{view.init}"/>
</f:metadata>

FYI, this post can help you too When to use f:viewAction / preRenderView versus PostConstruct?

not sure it is because of `f:metadata` because the method is called, however I am not sure about the order – matthias Mar 21 '18 at 15:02
It's probably been called during build time, that's why – Rapster Mar 21 '18 at 15:22
can I execute the init method before build time? – matthias Mar 22 '18 at 09:10
`getTimeZone` is a simple getter or it does more than that? If it's more than that, you should be more careful, see https://stackoverflow.com/questions/2090033/why-jsf-calls-getters-multiple-times – Rapster Mar 25 '18 at 12:14
