reRender, update Model and commandLink

[gledson.rabelo]

Hi,

I'm using the Seam EntityHome and Ajax4JSF for developing ajax enabled CRUDs with pagination.

The data table has checkboxs that the user can select to delete many entities.

When I clicked in the Delete Button ("Excluir") the value of checkboxs should be updated in model, the method #{questionarioHome.removeChecked} should be cleaned called and the form should be cleaned reRendered returning to first page of data table, respectively .

But, the values returned for #{questionarioHome.removeChecked} method are the values of first page and not of the current page.

I thinking that the Rerender operation is being executed before the update of the model and the call the method #{questionarioHome.removeChecked}.


I tried to use immediate=true in the commandLink, but the call of method #{questionarioHome.removeChecked} is executed before the update of the model and I don't get the selected values.

I am making made a mistake?

Please, could somebody help me?


My code is listed below:

 <a4j:form>

 <a4j:outputPanel id="listPanel" ajaxRendered="true" layout="block">

 <!-- search results -->

 <rich:dataTable value="#{questionarios.resultList}" var="questionario"
 id="table">
 <f:facet name="header">
 <rich:columnGroup>

 <rich:column>
 Seleção
 </rich:column>

 <rich:column>
 <a4j:commandLink value="-" reRender="listPanel">
 <f:param name="querySorting" value="descricao" />
 </a4j:commandLink>
 <h:outputText value="Descri&ccedil;&atilde;o" />
 </rich:column>
 <rich:column>
 <a4j:commandLink value="-" reRender="listPanel">
 <f:param name="querySorting" value="exercicio" />
 </a4j:commandLink>
 <h:outputText value="Exerc&iacute;cio" />
 </rich:column>
 </rich:columnGroup>
 </f:facet>

 <rich:column>
 <h:selectBooleanCheckbox value="#{questionarioHome.selection[questionario.idQuestionario]}" />
 </rich:column>

 <rich:column>
 <s:link view="/viewQuestionario.xhtml"
 value="#{questionario.descricao}">
 <f:param name="questionarioId"
 value="#{questionario.idQuestionario}" />
 </s:link>
 </rich:column>

 <rich:column>
 <h:outputText value="#{questionario.exercicio}" />
 </rich:column>

 </rich:dataTable>

 <h:outputText
 value="Não h&aacute; question&aacute;rios para seram exibidos."
 rendered="#{empty questionarios.resultList}" class="message" />


 <div class="tableControl"><h:outputText
 value="Total de Registros: ${questionarios.resultCount}" />

 <!-- Pagination Buttons -->

 <a4j:commandLink
 value="&lt;&lt;" reRender="listPanel" ajaxSingle="true"
 rendered="#{questionarios.previousExists}">
 <f:param name="firstResult" value="0" />
 <f:param name="querySorting" value="#{questionarios.order}" />
 </a4j:commandLink>

 <a4j:commandLink value="&lt;" reRender="listPanel" ajaxSingle="true"
 rendered="#{questionarios.previousExists}">
 <f:param name="firstResult"
 value="#{questionarios.previousFirstResult}" />
 <f:param name="querySorting" value="#{questionarios.order}" />
 </a4j:commandLink>

 <a4j:commandLink value="&gt;" reRender="listPanel" ajaxSingle="true"
 rendered="#{questionarios.nextExists}">
 <f:param name="firstResult" value="#{questionarios.nextFirstResult}" />
 <f:param name="querySorting" value="#{questionarios.order}" />
 </a4j:commandLink>

 <a4j:commandLink value="&gt;&gt;" reRender="listPanel" ajaxSingle="true"
 rendered="#{questionarios.nextExists}">
 <f:param name="firstResult" value="#{questionarios.lastFirstResult}" />
 <f:param name="querySorting" value="#{questionarios.order}" />
 </a4j:commandLink></div>

 <div class="actionButtons">

 <!-- Delete Button -->

 <a4j:commandLink action="#{questionarioHome.removeChecked}" value="Excluir">
 </a4j:commandLink>

 </div>
 </a4j:outputPanel>

 </a4j:form>

The stranger is that the list of dataTable (# {questionarios.resultList}) is loaded before calling the method # {questionarioHome.removeChecked}.

It seems that reRender of dataTable is happening before the action call and before of the update of selectBooleanCheckbox in the model.

Is it normal?


Thanks in Advance,
