Primefaces DataTable ajax not updating any component except itself

Question

<h:form id="form">
        <p:messages />
        <p:panel header="Análise">
            <h:outputText value="Mês da análise: " />

            <p:selectOneMenu value="#{report005.selectedMes}">
                <f:selectItems var="data" value="#{report005.analiseMeses}" itemLabel="#{report005.formataDataCombo(data)}" />
                <f:convertDateTime pattern="MM/yyyy" />
            </p:selectOneMenu>

            <p:commandButton value="Análises" update="analiseTable" actionListener="#{report005.loadAnalise()}" />

            <p:dataTable id="analiseTable" var="pes" value="#{report005.analiseModel}" selection="#{report005.selectedAnalise}" emptyMessage="Não há registros...">

                <p:column selectionMode="multiple" style="width:18px" />

                <p:ajax event="rowSelectCheckbox" listener="#{report005.loadAnaliseProduto()}" update="produtosmanycheck" />

                <p:column headerText="Código">  
                    #{pes.cod_analise}  
                </p:column>

                <p:column headerText="Nome">  
                    #{pes.dsc_analise}  
                </p:column>

                <p:column headerText="Descrição">  
                    #{pes.dsc_resumida_acao}  
                </p:column>

                <p:column headerText="Planejamento">
                    <h:outputText value="#{pes.dat_planejamento_analise}">
                        <f:convertDateTime pattern="dd/MM/yyyy" />
                    </h:outputText>
                </p:column>

            </p:dataTable>
        </p:panel>
        <p:panel header="Produto Gerencial">

            <p:selectManyCheckbox id="produtosmanycheck" value="#{report005.selectedProduto}" layout="pageDirection">
                <f:selectItems id="teste" value="#{report005.produtos}" />
            </p:selectManyCheckbox>

        </p:panel>
        <p:commandButton value="Enviar" action="#{report005.send}" ajax="false" />
    </h:form>

Whan the AJAX event "rowSelectCheckbox" is fired, it does not find the 'produtosmanycheck' component to update, returning the following error to me:

javax.faces.FacesException: Cannot find component with identifier "produtosmanycheck" referenced from "form:analiseTable". at org.primefaces.util.ComponentUtils.findClientIds(ComponentUtils.java:251) at org.primefaces.util.AjaxRequestBuilder.addIds(AjaxRequestBuilder.java:102) at org.primefaces.util.AjaxRequestBuilder.update(AjaxRequestBuilder.java:90)

I already tried= :form:produtosmanycheck, form:produtosmanycheck, :produtosmanycheck, produtosmanycheck

I tried removing the FORM id too... without success...

What am I doing wrong? I can't update any component but the DataTable...

@BalusC I opened the html of the generated page, and this is the code generated for my selectManyCheckbox: — BBacon, Oct 02 '12 at 11:57
when you look at the component in browser's page source what id do you see? — velo, Oct 02 '12 at 13:14
@Joshi its described 4 messages up this one.
... the aswer is then: form:produtosmanycheck. — BBacon, Oct 02 '12 at 13:40
@JordanDenison I removed the "father" form and it worked. I don't see why that's a problem, the prependId property was set to false and it refused to find the component either way. Please post your answer so I can mark it as correct. — BBacon, Oct 02 '12 at 14:04
You are welcome. Love it when I find the issue and someone else post it, or not even post it but edit the old **bad** answer:) — Fallup, Oct 02 '12 at 14:26

You can reach that produtosmanycheck using :form:produtosmanycheck

EDIT: Nested forms will not work properly and give all kinds of DOM issues like the one you're experiencing. Work out a way to separate your view components into separate forms and then try the above named access.

This should definitely work. If it is not working for you @MBarni , then you've checked it wrong or you have another problem. Try it once more, and see if javax.faces.FacesException appears or if it is just not updated. – Fallup Oct 02 '12 at 07:52
Nope. The problem persists: > javax.faces.FacesException: Cannot find component with identifier > ":form:produtosmanycheck" referenced from "form:analiseTable". at > org.primefaces.util.ComponentUtils.findClientIds(ComponentUtils.java:251) > at > org.primefaces.util.AjaxRequestBuilder.addIds(AjaxRequestBuilder.java:102) > at > org.primefaces.util.AjaxRequestBuilder.update(AjaxRequestBuilder.java:90) – BBacon Oct 02 '12 at 11:36
@MBarni set `prependId=false` on the form – kolossus Oct 02 '12 at 14:31
It's not about `id`s, nested forms are forbidden. – Fallup Oct 02 '12 at 14:38
@Fallup. I completely missed that in the question. Nested forms? Heck no! – kolossus Oct 02 '12 at 14:40
Because it wasn't in the question, read the comments under the question. – Fallup Oct 02 '12 at 14:41

Have you tried putting the id "produtosmanycheck" on the parent p:panel element instead of on the p:selectManyCheckbox itself?

Form nesting should never be done in JSF even with prepend ID false as it will cause unexpected or no behaviour.

Form nesting should be never done ever, not only in JSF. Also the first part of your answer has nothing to do with the actual problem. – Fallup Oct 02 '12 at 14:32

I will post my own answer (in the end I came up with nested forms idea) as well as voting up @kolossus because he was basically right and couldn't know about nested forms.

Nested forms aren't the "thing" of JSF only (as it may seem from @JordanDenison answer), it is a general rule of HTML --> nesting forms is forbidden in HTML !

You may want to read this nesting forms in HTML
