PrimeFaces - p:dataTable + p:confirmDialog + p:confirmDialog + f:setPropertyActionListener - Valor Null

[LoCo On Line]

Senhores,

Estou com o problema que parece ser o mais comum de todos, mas não encontro um solução.

Estou construindo uma tela que tem um form e dentro um p:dataTable, para ter a coluna de edição coloquei um p:commandLink que chama o p:confirmDialog para executar o <p:commandButton id="deleteConfirmation"

Tudo isso funciona, mas não consigo passar o ID de forma nenhuma para o bean

O <p:commandButton id="deleteConfirmation" chama o metodo, mas não pego o ID 

                                  <div class="table-responsive">

<h:form id="form">

<p:dataTable id="categoriesTable" var="category" value="#{categoriesView.allinLazyModel}" paginatorPosition="bottom" paginator="true"

paginatorTemplate="{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown} {CurrentPageReport}"

rowsPerPageTemplate="10,20,50" rows="10" lazy="true" sortBy="#{category.name}">

<p:column headerText="Id" style="width:60px;">

<h:outputText value="#{category.id}" />

</p:column>

<p:column headerText="#{messages.CategoryName}" sortBy="#{category.name}" filterBy="#{category.name}" styleClass="text-left">

<h:outputText value="#{category.name}" />

</p:column>

<p:column headerText="#{messages.CategoryFather}" sortBy="#{category.fatherName}" filterBy="#{category.fatherName}" styleClass="text-left">

<h:outputText value="#{category.fatherId} #{category.fatherName}" />

</p:column>

<p:column headerText="#{messages.CategoryOrderDisplay}" sortBy="#{category.orderDisplay}" filterBy="#{category.orderDisplay}" styleClass="text-left">

<h:outputText value="#{category.orderDisplay}" />

</p:column>

<p:column headerText="#{messages.CategoryVisible}" sortBy="#{category.visible}" filterBy="#{category.visible}" styleClass="text-left">

<h:outputText value="#{category.visible}" />

</p:column>

<p:column headerText="Action" styleClass="text-right" style="width:120px;">

<h:link outcome="catalog/change/category" title="#{messages.Edit}">

<f:param name="id" value="#{category.id}" />

<i class="btn btn-primary fa fa-pencil"></i>

</h:link>

<p:commandLink icon="fa fa-trash-o" id="category-delete">

<p:confirm header="#{messages.Confirmation}" message="#{messages.Areyousuretoremove}" icon="ui-icon-alert" />

<f:setPropertyActionListener value="#{category.id}" target="#{categoriesRequest.id}" />

<i class="btn btn-danger fa fa-trash-o"></i>

</p:commandLink>

</p:column>

</p:dataTable>

<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" severity="alert">

<p:commandButton id="deleteConfirmation" value="#{messages.Yes}" styleClass="ui-confirmdialog-yes" icon="ui-icon-check"

action="#{categoriesRequest.delete}" />

<p:commandButton value="#{messages.No}" styleClass="ui-confirmdialog-no" icon="ui-icon-close" />

</p:confirmDialog>

</h:form>

</div>

Informações para debug:

* - Só existe um form em todo html

* - categoriesRequest é um bean do tipo @Request 

* - Já tentei colocar o p:confirmDialog ou os p:commandButton em outros forms

* - Já tentei colocar o f:setPropertyActionListener no p:commandButton

* - O p:commandLink já foi p:commandButton e mesmo assim não funciona

Estou usando o WildFly 8.x , primefaces-5.2.RC3 e o JSF 2.2.8

Por favor, alguém tem alguma ideia de como fazer isso funcionar?

Atenciosamente,

Bom dia!

Considerando que esteja tudo certo no seu controle.

Tente desta forma:

<p:column style="width:50px;" headerText="Excluir">

      <p:commandButton id="btnConfirmarExclusao" onclick="formCorpo:confirmacaoExclusao.show()" icon="ui-icon-trash">

  <f:setPropertyActionListener value="#{banco}" target="#{BancoControl.banco}" />

      </p:commandButton>

</p:column> 

<p:confirmDialog message="Confirma a exclusão deste registro?" header="Confirmação de exclusão" severity="alert" widgetVar="confirmacaoExclusao">

     <p:commandButton id="btnSim" value="Sim" oncomplete="confirmacaoExclusao.hide()" actionListener="#{BancoControl.excluir }" update="@form" />

     <p:commandButton id="btnNao" value="Não" onclick="confirmacaoExclusao.hide()" type="button" />

</p:confirmDialog>

Respondendo a mim mesmo... :)

Descobri o problema.

Como fica o form:

<h:form id="tabela">

<p:dataTable id="categoriesTable" var="category" value="#{categoriesView.allinLazyModel}" paginatorPosition="bottom" paginator="true"

paginatorTemplate="{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown} {CurrentPageReport}"

rowsPerPageTemplate="10,20,50" rows="10" lazy="true" sortBy="#{category.name}" reflow="true" resizableColumns="true">

<p:column headerText="ID" style="width:60px;">

<h:outputText value="#{category.id}" />

</p:column>

<p:column headerText="#{messages.CategoryName}" sortBy="#{category.name}" filterBy="#{category.name}" styleClass="text-left">

<h:outputText value="#{category.name}" />

</p:column>

<p:column headerText="#{messages.CategoryFather}" sortBy="#{category.fatherName}" filterBy="#{category.fatherName}" styleClass="text-left">

<h:outputText value="#{category.fatherId} #{category.fatherName}" />

</p:column>

<p:column headerText="#{messages.CategoryOrderDisplay}" sortBy="#{category.orderDisplay}" filterBy="#{category.orderDisplay}" styleClass="text-left">

<h:outputText value="#{category.orderDisplay}" />

</p:column>

<p:column headerText="#{messages.CategoryVisible}" sortBy="#{category.visible}" filterBy="#{category.visible}" styleClass="text-left">

<h:outputText value="#{category.visible}" />

</p:column>

<p:column headerText="Action" styleClass="text-right" style="width:120px;">

<h:link outcome="catalog/change/category" title="#{messages.Edit}">

<f:param name="id" value="#{category.id}" />

<i class="btn btn-primary fa fa-pencil"></i>

</h:link>

<p:commandLink id="category-delete" update=":tabela:categoriesTable" action="#{categoriesView.delete}">

<f:setPropertyActionListener value="#{category.id}" target="#{categoriesView.id}" />

<p:confirm header="#{messages.Confirmation}" message="#{messages.Areyousuretoremove}" icon="ui-icon-alert" />

<i class="btn btn-danger fa fa-trash-o"></i>

</p:commandLink>

</p:column>

</p:dataTable>

<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" severity="alert">

<p:commandButton id="deleteConfirmation" value="#{messages.Yes}" styleClass="ui-confirmdialog-yes" icon="ui-icon-check" />

<p:commandButton value="#{messages.No}" styleClass="ui-confirmdialog-no" icon="ui-icon-close" />

</p:confirmDialog>

</h:form>

O que muda é que todos os bean envolvidos tem que ser do tipo @ViewScoped

Isso por causa do ajax.

Valeu pessoal.
