Richface editable table problmes

[chanjob]

hi, I am using richfaces version:richfaces-api-3.3.2.SR1

My page have a list of report record, it has a checkbox for each record.

The datatable code:

<rich:dataTable

                                    id="resultTable"

                                    columnClasses="rsCol1,rsCol2"

                                    value="#{reportTypeEmailBean.reportTypeEmailList}"

                                     var="report"

                                     border="0"

                                     cellspacing="0"

                                     cellpadding="0"

                                     rowClasses="evenCol, oddCol"

                                     headerClass="rsHeader"

                                     rows="#{reportTypeEmailBean.reportTypeEmaillListMaxRows}"

                                     width="1100"

                                 >

                                     <rich:column>

                                        <f:facet name="header" >

                                            Report Name

                                        </f:facet>

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

                                       </rich:column>

                                       <rich:column>

                                        <f:facet name="header" >

                                                <h:panelGroup>

                                                    <div style="float:left; width:53px;display:block; ">

                                                        Report<br/>Email<br/>Alert

                                                    </div>

                                                    <div style="float:left; width:20px;display:block">

                                                         <h:selectBooleanCheckbox  value="#{reportTypeEmailBean.checkAll}" style="margin-top:16px">

                                                            <a4j:support onsubmit="ON_WAITING_STATUS=true;" event="onclick" oncomplete="checkAll(#{reportTypeEmailBean.checkAll})"  />

                                                        </h:selectBooleanCheckbox>

                                                    </div>   

                                                    <div style="float:left; width:40px;display:block;margin-left:10px;margin-top:4px">

                                                        <a4j:jsFunction id="saveFunc"   name="save" action="#{reportTypeEmailBean.save}"/>

                                                        <a4j:commandButton id="saveBtnCmd" onclick="save()" style="width:40px"

                                                        image="#{facesContext.externalContext.requestContextPath}/img/Save-icon.png"

                                                        reRender ="saveEmailIndModelPanel"

                                                        oncomplete="

                                                            Richfaces.showModalPanel('saveEmailIndModelPanel');

                                                        "

                                                        title="Save"

                                                         >   

                                                        </a4j:commandButton>

                                                    </div>

                                                 </h:panelGroup>

                                       </f:facet>

                                        <h:selectBooleanCheckbox id="eind" value="#{report.emailBooleanInd}" style="margin-left:57px">

                                            <a4j:support onsubmit="ON_WAITING_STATUS=false;"   event="onclick"/>

                                        </h:selectBooleanCheckbox>

                                       </rich:column>

                                 </rich:dataTable>

The datascroller  code:

<rich:datascroller for="resultTable" id="ds">

               <a4j:support event="onpagechange"/>

</rich:datascroller>  

As I change page, sometime the all things works fine; but if I change the page faster.

Sometime the checkbox will uncheck for whole page. I don't know why that would happen and how to avoid.

Please help. Thanks.
