Referencing managed bean as composite attribute and invoking its method causes MethodNotFoundException

Question

I'm trying to create a composite component receveing some arguments like my ManagedBean.

This is my composite component:

<composite:interface>
    <composite:attribute name="label" required="true"
        shortDescription="Valor que será mostrado no campo. Ex: Id" />
    <composite:attribute name="methodName" required="true"
        shortDescription="Nome do método que realiza o get ao campo. Ex: getId" />
    <composite:attribute name="managedBeanName"
        type="br.com.jwebbuild.mb.BasicCrudMBImpl" required="true"
        shortDescription="Nome do managedBean do componente" />
</composite:interface>

<composite:implementation>

    <h:commandLink value="#{cc.attrs.label}"
        actionListener="#{cc.attrs.managedBeanName.orderby(cc.attrs.methodName)}"
        title="Clique para ordernar">
        <f:ajax execute="@this" render="@form" />
    </h:commandLink>
    <i class="fa fa-bars fa-fw"></i>

</composite:implementation>

When i try to execute i got error: MethodNotFoundException. But if i change this line

    actionListener="#{cc.attrs.managedBeanName.orderby(cc.attrs.methodName)}"

for this:

    actionListener="#{bancaMB.orderby(cc.attrs.methodName)}"

Everything works fine, but why my composite don't works with cc.attrs ? I have anothers composite components that receive same ManagedBean and works fine.

Look, in this code i'm using this composite component:

<jw:orderColumLink managedBeanName="#{bancaMB}"
                                                    methodName="getId" label="Id" />

Edit 1

This code bellow works normal, and use managedBean parameter method:

<composite:interface>
    <composite:attribute name="idDataTable" default="dataTableListagem"
        shortDescription="ID do DataTable. Usado para referencia em outras partes do código" />
    <composite:attribute name="managedBeanName"
        type="br.com.jwebbuild.mb.BasicCrudMBImpl" required="true"
        shortDescription="Nome do managedBean do componente" />

    <composite:attribute name="showSelectAll" type="boolean" default="true"
        shortDescription="Mostra a coluna para selecionar todos os registros. Padrão = true" />

    <composite:attribute name="showEditRemove" type="boolean"
        default="true"
        shortDescription="Mostra a coluna para editar e remover um registro. Padrão = true" />

    <composite:attribute name="targetPage" type="String"
        shortDescription="Caminho para acesso a página de inserção ou alteração do registro." />

</composite:interface>

<composite:implementation>

    <div class="table-responsive">
        <h:dataTable var="bean" value="#{cc.attrs.managedBeanName.beans}"
            id="#{cc.attrs.idDataTable}" styleClass="table table-hover"
            binding="#{cc.attrs.managedBeanName.dataTable}">
            <h:column rendered="#{cc.attrs.showSelectAll}"
                headerClass="smallColumn">
                <f:facet name="header">
                    <h:selectBooleanCheckbox
                        valueChangeListener="#{cc.attrs.managedBeanName.selectAll}">
                        <f:ajax execute="@form" render="@form" />
                    </h:selectBooleanCheckbox>
                </f:facet>

                <h:selectBooleanCheckbox value="#{bean.selected}">
                    <f:ajax execute="@this" render="@this" />
                </h:selectBooleanCheckbox>
            </h:column>

            <composite:insertChildren />

            <h:column rendered="#{cc.attrs.showEditRemove}"
                headerClass="smallColumn">
                <h:link styleClass="btn btn-default"
                    outcome="#{cc.attrs.managedBeanName.redirectAlterarBean(cc.attrs.targetPage,bean.id)}">
                    <i class="fa fa-pencil-square-o fa-lg"></i> Editar
                    </h:link>
            </h:column>

        </h:dataTable>
    </div>
    <!-- /.table-responsive -->
</composite:implementation>

Should work fine and works just fine for me on Tomcat 8 and WildFly 8. Which JSF/container/EL impl/version are you using? Can you please post the full stack trace? — BalusC, Feb 18 '15 at 07:41
@BalusC, I edited my post with full StackTrace and informations about JSF version — Shelly, Feb 18 '15 at 16:45
@BalusC, I beleive that if you said it should work fine then it should work fine, but for my understanding I read that for methods to work inside composite implementation we need to provide method-signature, also in the Java EE 6 tutoriel they only talk about bean properties when talking about passing a managed bean. So could you explain to me why that should work? thanks — Tarik, Feb 18 '15 at 17:33
@Tarik, i can ensure that works, i can call method using ManagedBean as parameter. — Shelly, Feb 18 '15 at 17:41
@Shelly Yes I do beleive that, I just hope to understand more from BalusC, that's why my question :) (I removed my answer as it's not correct and may mislead other SO users) — Tarik, Feb 18 '15 at 17:44
I see that you're using Tomcat. Which version exactly? Older versions had similar bugs in their Apache EL impl. The second example "works fine" because `` just evaluates as a value expression returning a `String`, not as a method expression which should invoke an action method. You should also have noticed that the `` expression was invoked during rendering the HTML output, not during clicking the link. — BalusC, Feb 18 '15 at 18:18
Right, i will upgrade test again and return here with a feedback. — Shelly, Feb 18 '15 at 18:24
@Tarik: you can actually parameterize bean, method and arguments separately like OP did. See also a.o. http://stackoverflow.com/q/11994339 and http://stackoverflow.com/q/13748019 Only, I'd rename that confusing attribute name `managedBeanName` to `managedBean` as it actually refers a managed bean instance, not a plain vanilla string representing managed bean name ;) — BalusC, Feb 18 '15 at 18:25
I finally found the related/duplicate question: http://stackoverflow.com/q/4385545 In the comment of my answer you can see that it's fixed in 7.0.24, along with a link to another question concerning the same problem http://stackoverflow.com/q/8795009/ @Shelly, which do you accept as duplicate? — BalusC, Feb 18 '15 at 18:27
@BalusC, let me try first but i can't accept as duplicate because i didn't know the cause of problem. — Shelly, Feb 18 '15 at 18:42
@Shelly he told you that the cause of your problem is a bug in EL implementation of Tomcat, and in his answers, he provided the link to the issue: https://bz.apache.org/bugzilla/show_bug.cgi?id=50449 — Tarik, Feb 18 '15 at 19:32
I know that Tarik, ready again my answer. I told that i "didn't know" but now i know. — Shelly, Feb 18 '15 at 19:41
@BalusC, i tested with new tomcat 7.0.59 version and worked very well, thanks for help. — Shelly, Feb 18 '15 at 22:39
