<f:viewAction> included into facelets template client does not work

305 Views Asked by At

just a question....don't know if I did it right or if this will not work by specs. I've made a simple facelets master template, like this:

template.xhtml

    <html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core">

    <f:view>
        <ui:insert name="metadata" />

        <h:head>    

....  here the rest of template with other <ui:insert>

The client is simple and uses the template:

main.xhtml

<ui:composition xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
                xmlns:f="http://xmlns.jcp.org/jsf/core"
                xmlns:h="http://xmlns.jcp.org/jsf/html"
                template="./WEB-INF/template/template.xhtml">

    <ui:define name="metadata">        
        <ui:include src="./WEB-INF/template/securityCheck.xhtml" />
    </ui:define>

... here goes the rest with other <ui:define> and <ui:include> ....

In the securityCheck.xhtml lies the simple f:viewAction as follow:

securityCheck.xhtml

<ui:composition xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
                xmlns:f="http://xmlns.jcp.org/jsf/core">

    <f:metadata>
        <f:viewAction action="#{loginController.doLoginCheck()}" />
    </f:metadata>
</ui:composition>

Well, in this cas the f:viewAction is not ivoked, instead if I expand into metadata section the code directly, as follow:

main.xhtml

<ui:composition xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
                xmlns:f="http://xmlns.jcp.org/jsf/core"
                xmlns:h="http://xmlns.jcp.org/jsf/html"
                template="./WEB-INF/template/template.xhtml">

    <ui:define name="metadata">        
        <f:metadata>
            <f:viewAction action="#{loginController.doLoginCheck()}" />
        </f:metadata>
    </ui:define>

... here goes the rest with other <ui:define> and <ui:include> ....

it works like a charm (as expected). Why is the inclusion of the metadata section into template client not working? And if there is a correct way to do this how can I add other f:viewAction calls after the included one? Something like this:

otherpage.xhtml

<ui:composition xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
                xmlns:f="http://xmlns.jcp.org/jsf/core"
                xmlns:h="http://xmlns.jcp.org/jsf/html"
                template="./WEB-INF/template/template.xhtml">

    <ui:define name="metadata"> 
        <ui:include src="./WEB-INF/template/securityCheck.xhtml" />
        <f:metadata>
            <f:viewAction action="#{myBean.doSomething()}" />
        </f:metadata>
    </ui:define>

... here goes the rest with other <ui:define> and <ui:include> ....

If this is correct, are the calls made in this specific order?

I'm using JavaEE 7/JSF 2.2 with Glassfish 4.1 and Mojarra 2.2.12 impl.

Thank you.
