Question

I need to set a dynamic page title to the page which is retrieved after preRenderView & preRenderComponent’s listeners inside document body have been executed. But I find that title is rendered before those listeners were executed.

Is there any way I could delay the rendering of title tag until listeners have executed ?

Ok, I tried following strategy as a workaround. I just move f:event type="preRenderComponent".. from inside body to head section & I get the desired behavior.

<f:metadata>
    <f:viewParam name="id" value="#{bean.id}" />
</f:metadata>

<ui:define name="titleOfPage">
    <f:event type="preRenderComponent" listener="#{bean.method()}"/>
    #{bean.title}
</ui:define>

<ui:define name="bodyOfPage">
    ..
    ..
</ui:define>

master template:

<h:head>
    ... 
    <title><ui:insert name="titleOfPage"></ui:insert></title>
</h:head>
<h:body >
     <ui:insert name="bodyOfPage">Body of the pages goes here</ui:insert>
</h:body >

First listener method is invoked & then title inside head is rendered.

Perhaps PreRenderView type could have been used directly without requiring to move the f:event tag to head but PreRenderView is triggered even on ajax requests which is not desired.
