Command Lnks inside DataTable

deibys Jan 24, 2008 1:24 PM

Hello Guys!!
I have the following code :

<rich:dataTable id="prospectoTable" value="#{SearchProspecto.prospectoItems}"
 var="prospecto" rowKeyVar="index"
 onRowMouseOver="this.style.backgroundColor='#FFE4E1'"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'" >
 <h:column>
 <f:facet name="header">
 <h:outputText value="#" />
 </f:facet>
 <h:outputText value="#{index+1}" />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Identificacion" />
 </f:facet>
 <h:outputText value="#{prospecto.identificacion}" />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Nombre" />
 </f:facet>
 <h:outputText value="#{prospecto.fullName}" />
 </h:column>
 <h:column>
 <h:form>
 <a4j:region>
 <a4j:commandLink immediate="true" value="Editar" action="#{SearchProspecto.editar}" >
 <a4j:actionparam name="prospectoIdSelected" assignTo="#{SearchProspecto.prospectoIdSelected}" value="#{prospecto.id}" />
 </a4j:commandLink>
 </a4j:region>
 </h:form>
 </h:column>
 <%--
 <rich:componentControl event="onRowDblClick" for="propectoDetails" operation="show">
 <f:param value="#{prospecto.id}" name="prospectoId" />
 </rich:componentControl>
 --%>
</rich:dataTable>

One of the columns (violet colour) has a command link.....that calls a method in the backing bean

public String editar() throws NamingException, SQLException {
 System.out.println("prospecto_id="+prospectoIdSelected);
 Prospecto prospecto = Prospecto.getProspectoById(prospectoIdSelected);
 FacesUtil.setRequestMapValue("prospecto", prospecto);
 if (prospecto.getTipoCliente() == 1) {
 return "editar_empresarial";
 } else {
 return "editar_individual";
 }
 }

I have two weird issues:

1. Only the last row of the table seems to call the method specified in the action attribute

2. When I click on the link on the last row , method gets called, but it does not navigate according to my rules in faces-config.xml

<navigation-rule>
 <from-view-id>/Prospectacion/searchProspecto.jsp</from-view-id>
 <navigation-case>
 <from-outcome>editar_empresarial</from-outcome>
 <to-view-id>/Prospectacion/editProspecto_e.jsp</to-view-id>
 </navigation-case>
 <navigation-case>
 <from-outcome>editar_individual</from-outcome>
 <to-view-id>/Prospectacion/editProspecto_i.jsp</to-view-id>
 </navigation-case>
 </navigation-rule>

Why this stranged behaviour ?

Having form inside the table column is a bad idea in general.

Why you use Ajax command link if you expect non-Ajax response (using the navigation rule) ?

If it is bad idea , what is the way to go ? in my application i need to have a submit element inside a table , one per each element...
For instance, I have a table of clientes, and when i click on the "edit" button present in every row....It should go to the "edit client" view

I use a4j:commandButton or link, because I want my application to have a non-reload page feeling, so...almost every request is done by ajax

I have put the form outside of the dataTable and it does not work at all. In no case the action method is called

<h:form>
<rich:messages />
<rich:dataTable id="prospectoTable" value="#{SearchProspecto.prospectoItems}"
 var="prospecto" rowKeyVar="index"
 onRowMouseOver="this.style.backgroundColor='#FFE4E1'"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'" >
 <h:column>
 <f:facet name="header">
 <h:outputText value="#" />
 </f:facet>
 <h:outputText value="#{index+1}" />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Identificacion" />
 </f:facet>
 <h:outputText value="#{prospecto.identificacion}" />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Nombre" />
 </f:facet>
 <h:outputText value="#{prospecto.fullName}" />
 </h:column>
 <h:column>
 <a4j:commandButton immediate="true" value="Editar" action="#{SearchProspecto.editar}" >
 <a4j:actionparam name="prospectoIdSelected" assignTo="#{SearchProspecto.prospectoIdSelected}" value="#{prospecto.id}" />
 </a4j:commandButton>
 </h:column>
 <%--
 <rich:componentControl event="onRowDblClick" for="propectoDetails" operation="show">
 <f:param value="#{prospecto.id}" name="prospectoId" />
 </rich:componentControl>
 --%>
</rich:dataTable>
</h:form>

Thanks in advance for any help
