Primefaces datatable is not populating with the list from backing bean

I have a feedBackSearchList as follows,

List feedBackSearchList;

I'm trying to set this list to populate in datatable in my xhtml page.

setFeedBackSearchList(getFeedbackSearchService().getSearchResult(
                idemployee, idCliente, applicId, idEst, estId, idtecnologia));

I got the list from database, but it is not showing in xhtml page.

Please help me. The xhtml page is as follows,

<p:dataTable id="feedBackResultTab" var="feedBackResult" dynamic="true" value="#{feedbackSearchView.feedBackSearchList}" >
<p:column>
<f:facet name="header">
<h:outputText value="Employee" />
</f:facet>
<f:facet name="output">
<h:outputText value="#{feedBackResult.employeename}" />
</f:facet>
    </p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Client" />
</f:facet>
    <f:facet name="output">
<h:outputText value="#{feedBackResult.desCliente}" />
</f:facet>
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Application" />
        </f:facet>
<f:facet name="output">
<h:outputText value="#{feedBackResult.applicationDesc}" />
        </f:facet>
    </p:column>
    <p:column>
                <f:facet name="header">
                            <h:outputText value="Estimation Methode" />
                        </f:facet>
                        <f:facet name="output">
                                <h:outputText value="#{feedBackResult.desMethodEst}" />
                            </f:facet>
                    </p:column>
                    <p:column>
                        <f:facet name="header">
                            <h:outputText value="Technology" />
                        </f:facet>
                        <f:facet name="output">
                                <h:outputText value="#{feedBackResult.destecnologia}" />
                            </f:facet>
                    </p:column>
                    <p:column>
                        <f:facet name="header">
                            <h:outputText value="Date" />
                        </f:facet>
                        <f:facet name="output">
                                <h:outputText value="#{feedBackResult.fechaultimaactualizacion}" />
                            </f:facet>
                    </p:column>

                </p:dataTable>

Please help where I have done the mistake.

you access the objects like in an array instead of feedBackResult.desMethodEst just feedBackResult[0]

You should not populate the list in the setter method. JSF will call the getter-method of your list if it builds the datatable. So you should either populate the list in the getFeedBackSearchList or (and even better): in a method populateFeedbackSearchList at bean construction time.

UPDATE:

Ok, you should change your columns like this:

<p:column>
  <f:facet name="header">
    <h:outputText value="Employee" />
  </f:facet>
  <h:outputText value="#{feedBackResult.employeename}" />
</p:column>

No facet is needed for the cell content, only for the header.
