Primefaces DataTable ajax not updating any component except itself - jsf

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)

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...

Answer 1

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.

Answer 2

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.

Answer 3

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 !
