DataExporter not working for filtered dataTable in Primefaces 3.2

Question

In my application I am using global filter for searching the records in Primefaces DataTable and I have applied DataExporter on the same DataTable.

When I Search any record and go for export, it return me a complete list of data instead of filtered list.

My development environment is: java 6.0, Primefaces 3.2, JSF2.1, GlassFish Server 3.1.2, Netbeans 7.1.1

Enlisted below my dataTable and dataExporter code.

My dataTable code is::

 <p:dataTable value="#{personnelController.allItems}" 
                                     emptyMessage="#{bundle.PersonnelEmpty}"

                            </p:column>

                        </p:dataTable>

I am exporting table data from outside the dataTable as::

 <h:commandLink>  
      <p:graphicImage value="#{resource['images:excel.png']}" />  
      <p:dataExporter type="xls" target=":personnel:tbl" fileName="personnel" />  
 </h:commandLink>  

Please suggest me if I am doing anything wrong.

Answer 1

In the pom.xml:

<dependency>
   <groupId>org.apache.poi</groupId>
   <artifactId>poi</artifactId>
   <version>3.10.1</version>
</dependency>

<dependency>
   <groupId>com.itextpdf</groupId>
   <artifactId>itextpdf</artifactId>
   <version>5.5.3</version>
</dependency>

And replace:

<h:commandLink>  
      <p:graphicImage value="#{resource['images:excel.png']}" />  
      <p:dataExporter type="xls" target=":personnel:tbl" fileName="personnel" />  
 </h:commandLink>

 <h:commandLink>  
      <h:graphicImage value="#{resource['images:excel.png']}" />  
      <p:dataExporter type="xls" target=":personnel:tbl" fileName="personnel" />  
 </h:commandLink>

Answer 2

This is my example of a usertable:

<p:dataTable id="table" value="#{myBean.users}" var="usr" rowKey="#{usr.username}" widgetVar="usrwv">
        <f:facet name="header">  
            <p:outputPanel>  
                 <h:outputText value="Search all fields:" />  
                 <p:inputText id="globalFilter" onkeyup="usrwv.filter()" style="width:150px" />  
            </p:outputPanel>  
        </f:facet>
        <p:column headerText="Username" sortBy="#{usr.username}" filterBy="#{usr.username}">
               <f:facet name="header">  
                     Username
               </f:facet>
               <h:outputText value="#{usr.username}"/>
        </p:column>
        <p:column headerText="Role" sortBy="#{usr.role}" filterBy="#{usr.role}">
                <f:facet name="header">  
                     Role
                </f:facet>
                <h:outputText value="#{usr.role}"/>
        </p:column>
        <f:facet name="footer">
                <h:commandLink>  
                     <p:graphicImage value="/resources/images/excel.ico" title="myExcel"/>
                     <p:dataExporter type="csv" target="table" fileName="all_users"/>  
                </h:commandLink>
        </f:facet>
</p:dataTable>

Also you are putting the exporter and the datatable in two different forms. Try putting them in the same form. This should work.
