I have a datatable presented within a Dialog primefaces, when I click on commandLink of the line I desire, I want to take that value and render it within a inputText from my screen, but I’m getting the following error in my event update.

error: javax.faces.Facesexception: Cannot find Component with Expression "gerSup"

'Cause he’s not identifying my id inputText? I don’t know if it’s possible to do what I’m trying to do, but if anyone knows I could get the tip.

My inputText on the main screen

<p:inputText id="gerSup" value="#{funcionarioBean.funcionario.pessoa.nomePessoa}" style="width:270px; margin-left: 6px;"/>

Man p:dialog where I click on commandLink first column

<p:dialog header="Buscar Gerentes Cadastrados" height="300" width="750" widgetVar="gerDialog" modal="true" showEffect="drop" hideEffect="drop" resizable="false">
  <br/>
  <p:outputPanel id="getDetail" style="text-align:center;">

    <h:panelGrid columns="3">
      <h:outputText value="Buscar Gerente: " style="margin-left: 8px;" />
      <p:spacer width="5" />
      <p:inputText style="width:250px;" onkeyup="this.value = this.value.toUpperCase()" />
    </h:panelGrid>
    <br/>

    <p:dataTable var="obj" value="#{funcionarioBean.listGerentesSupervisores}" rows="5" paginator="true" paginatorPosition="bottom">
      <f:facet name="header">
        Gerentes e Supervisores
      </f:facet>
      <p:column width="5%" style="text-align:center">
        <p:commandLink value="Submit" update="gerSup">
          <p:graphicImage value="/resources/img/icon/Accepted16X16.png" />
        </p:commandLink>
      </p:column>

      <p:column headerText="Código" width="10%;" style="text-align:center">
        <h:outputText value="#{obj.pessoa.codigoPessoa}" />
      </p:column>
      <p:column headerText="Nome" width="40%;" style="text-align:center">
        <h:outputText value="#{obj.pessoa.nomePessoa}" />
      </p:column>
      <p:column headerText="Cargo" width="40%;" style="text-align:center">
        <h:outputText value="#{obj.cargo.descricao}" />
      </p:column>
    </p:dataTable>
  </p:outputPanel>
</p:dialog>

  • Ederson, this component with id gerSup is outside the p:dialog?

  • Yes Wakim, you are.

  • Ederson, the problem is that this way, it does the search only from the nearest Namingcontainer (Dialog), for this you need to follow the rule: :NamingContainerId:OutroNamingContainerId:<quantos mais>:seuComponente or, I believe, that only :seuComponente must resolve. Take a look at this post for more details: http://blog.primefaces.org/? p=2740

  • Thanks, I’ll test, already tried :gerSup and also did not work as it also did not work this way :formFun :gerSup. I will read the post, thanks!

Test as follows:

update="@form:gerSup"

In some versions jsf works with space.

update="@form gerSup"

Also test in place of @form the id of your form.

Take the test and tell us if it worked.
