从 primefaces 数据表创建复合组件时出现以下错误。我做错了什么!?

Exception 

javax.faces.view.facelets.TagException: /view/restrito/basico/municipio.xhtml @77,165 <p:ajax> Composite component does not support event rowSelect

tabela-padrao.xhtml

使用复合组件/使用组件

<h:form id="tabela-municipio">
<ezcomp:tabela-padrao value="#{municipioMB.listaMunicipios}"
uniqueId="id-tabela-municipio"
var="mun"
primaryKey="#{mun.id}"
selection="#{municipioMB.municipio}"
exportedFileName="municipios">
<p:ajax event="rowSelect" listener="#{municipioMB.onRowSelect}" update="@(form[id*='frm-municipio']),@(form[id*='tabela-municipio'])" />
<p:ajax event="rowUnselect" listener="#{municipioMB.onRowUnselect}" update="@(form[id*='frm-municipio']),@(form[id*='tabela-municipio'])" />
<p:column headerText="Pais" width="300" filterBy="#{mun.estado.pais.nome}" filterMatchMode="contains">
<h:outputText value="#{mun.estado.pais.nome}"/>
</p:column>
<p:column headerText="Estado" width="300" filterBy="#{mun.estado.sigla} - #{mun.estado.nome}" filterMatchMode="contains">
<h:outputText value="#{mun.estado.sigla} - #{mun.estado.nome}"/>
</p:column>
<p:column headerText="Município" filterBy="#{mun.nome}" filterMatchMode="contains">
<h:outputText value="#{mun.nome}"/>
</p:column>
</ezcomp:tabela-padrao>
</h:form>

最佳答案

您必须在复合组件中创建和注册自定义事件,并将相应的操作传递给数据表。由于 rowSelect 和 rowUnselect 事件是在数据表而不是复合组件上注册的。使用 clientBehavior 为复合组件注册事件。

<cc:interface>
...
<cc:clientBehavior name="customRowSelectEvent" targets="idOfDataTable" event="rowSelect" />
<cc:clientBehavior name="customRowUnselectEvent" targets="idOfDataTable" event="rowUnselect" />
</cc:interface>
  1. 名称是自定义事件的名称。
  2. targets 是您要为其实际注册操作的组件的 ID。在你的数据表的情况下。
  3. event 是您要为数据表注册的实际事件。

现在为复合组件注册事件。

<ezcomp:tabela-padrao ....>
<f:ajax event="customRowSelectEvent" listener="#{municipioMB.onRowSelect}" update="@(form[id*='frm-municipio']),@(form[id*='tabela-municipio'])" />
<f:ajax event="customRowUnselectEvent" listener="#{municipioMB.onRowUnselect}" update="@(form[id*='frm-municipio']),@(form[id*='tabela-municipio'])" />
.....
</ezcomp:tabela-padrao>
