Richface datatable filter and sorting

Version 2

    I have try to custom a filter like following

     

    <rich:column sortBy="#{report.dispReportName}" filterMethod="#{viewReportBean.filterStates}">

                                        <f:facet name="header">

     

                                             <h:panelGroup>

                                                  Report Name

                                            <h:inputText value="#{viewReportBean.filterValue}" id="input"  onclick="Event.stop(event);">

                                                 <a4j:support event="onblur" reRender="resultTable,ds"

                                                ignoreDupResponses="true" requestDelay="700"

                                                />

                                             </h:inputText>

     

                                             </h:panelGroup>

     

                                        </f:facet>

                                        <h:outputText value="#{report.dispReportName}"/>

      </rich:column>

     

    I key-in the filter, then filtered data show.  And I click the sorting icon,  i don't know why the table list all result (ignore the filter).

     

    as i click sorting icon, How can I just sort the filtered data? not all data?

     

    Please Help.Thanks.
