problem in using "x:dataTable" and "x:updateActionListener"

[Farooq Mahmood]

Hi,
I am new to jsf and I m using my faces. I m getting
problem regarding  "x:dataTable" and
"x:updateActionListener". I am actually I have seen
some posts regarding "x:dataTable" and
"x:updateActionListener" but I donot able to solve my
problem. Plz chk this problem and tell me where I m
doing wrong. 
The problem is that when I click on the link instead
of send that particular row (or taskId) it sends the
whole List and then it iterate the whole list and
display the list row values on the next page. Here is
the code:

inbox.jsp

                <x:dataTable id="data"
                        styleClass="scrollerTable"
                       
headerClass="standardTable_Header"
                       
footerClass="standardTable_Header"
                       
rowClasses="standardTable_Row1,standardTable_Row2"
                       
columnClasses="standardTable_Column,standardTable_ColumnCentered,standardTable_Column"
                        var="task"
                       
value="#{inboxTaskBean.taskList}"
                        preserveDataModel="true"
                        rows="10"
                   >

                   <h:column>
                       <f:facet name="header">
                          <h:outputText
value="#{messages['label_taskId']}" />
                       </f:facet>
                       <h:outputText
value="#{task.taskId}" />
                   </h:column>

                   <h:column>
                       <f:facet name="header">
                          <h:outputText
value="#{messages['label_weburi']}" />
                       </f:facet>
                               
                     <x:commandLink action="task"
immediate="true" >
                               <h:outputText
value="#{task.webFormURI}" />

                               <x:updateActionListener
property="#{taskForm.taskId}" value="#{task.taskId}"
/>
                       </x:commandLink>

                   </h:column>

                </x:dataTable>
