Primefaces DataTable Ajax不更新除自身以外的任何组件 [英] Primefaces DataTable ajax not updating any component except itself

问题描述

<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>

当AJAX事件"rowSelectCheckbox"被触发时，它找不到要更新的"produtosmanycheck"组件，因此向我返回了以下错误:

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:找不到带有标识符的组件 从"form:analiseTable"引用的"produtosmanycheck".在 org.primefaces.util.ComponentUtils.findClientIds(ComponentUtils.java:251) 在 org.primefaces.util.AjaxRequestBuilder.addIds(AjaxRequestBuilder.java:102) 在 org.primefaces.util.AjaxRequestBuilder.update(AjaxRequestBuilder.java:90)

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)

我已经尝试过=:form:produtosmanycheck，form:produtosmanycheck，:produtosmanycheck，produtosmanycheck

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

我也尝试删除FORM ID ...没有成功...

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

我做错了什么?除了DataTable，我无法更新任何组件.

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

推荐答案

您是否尝试将ID"produtosmanycheck"放在父级p:panel元素上，而不是放在p:selectManyCheckbox本身上?

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

即使前缀ID为false，也绝不能在JSF中完成表单嵌套，因为这会导致意外或无行为.

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