    rich:extendedDataTable firing dataModel unnecessarily

    Patrick Tilsworth Newbie
      I've been using the extendedDataTable on multiple tabs and I have been finding what I think are unncessary calls to fetch the dataModel. 
      I'm aware that a fix for this was part of 3.3.1 (RF-3341).  I checked out the tests 3341/Bean.java & Capital.java, along with the 3341/rf3341.xhtml to see if I could manually pass the test that was used for the release.
      From what I can determine from the test, the getCapitals() method (dataTable on tab1) is expected to
      a) fire for the blur event once if the rendered checkbox is unchecked(renderRegionOnly=false), and
      b) shouldn't fire at all if checked(renderRegionOnly=true).
      What I am seeing for a rich:dataTable on the blur event is:
      a) 3 times for unchecked(renderRegionOnly=false), and
      b) 2 times for checked(renderRegionOnly=true).
      (It fires once for submission of the form for either a or b).
      For the rich:extendedDataTable on the blur event I found:
      a) 3 times for unchecked
      b) 3 times for checked 
      It also fires 2 times for submission of the form for either a or b.
      The results don't seem to be what I'd expect from how I can see the test was formed.  I've also attempted using the "limitToList" option as well but with no luck.  Anyone else experiencing similar issues?

          It's official solution. if you using limittolist=true on control - dataTable should not call for model on requests from the control. So please show your code if it's fails for you.

           

          Also you could check the second workaround with region - but it's not really convenient for all the cases.

            here's the code:

             

            <rich:tabPanel switchType="ajax" selectedTab="#{bean.selectedTab}" id="tabPanel" >
            
            <rich:tab id="tab1" label="First" limitToList="true" reRender="dt1">
            
            <h:form id="f1">
            <rich:extendedDataTable id="dt1" value="#{bean.capitals1}" var="cap1" >
            <rich:column> 
            <h:outputText value="#{cap1.name}" />
            </rich:column> 
            </rich:extendedDataTable>
            </h:form> 
            </rich:tab> 
            
            <rich:tab id="tab2" label="Second" limitToList="true" reRender="dt2" >
            
            <h:form id="f2">
            <rich:extendedDataTable id="dt2" value="#{bean.capitals2}" var="cap2" >
            <rich:column> 
            <h:outputText value="#{cap2.name}" />
            </rich:column> 
            </rich:extendedDataTable>
            </h:form> 
            
            </rich:tab> 
            
            <rich:tab id="tab3" label="Third" name="tab3" limitToList="true" reRender="f3" >
            <h:form id="f3">
            This is the third tab
            </h:form> 
            </rich:tab> 
            
            </rich:tabPanel>
            
            
            
            
            
            
            
            
            
            
            

             

            <rich:tabPanel switchType="ajax" selectedTab="#{bean.selectedTab}" id="tabPanel" >
            
            <rich:tab id="tab1" label="First" limitToList="true" reRender="dt1">
            
            <h:form id="f1">
            <rich:extendedDataTable id="dt1" value="#{bean.capitals1}" var="cap1" >
            <rich:column> 
            <h:outputText value="#{cap1.name}" />
            </rich:column> 
            </rich:extendedDataTable>
            </h:form> 
            </rich:tab> 
            
            <rich:tab id="tab2" label="Second" limitToList="true" reRender="dt2" >
            
            <h:form id="f2">
            <rich:extendedDataTable id="dt2" value="#{bean.capitals2}" var="cap2" >
            <rich:column> 
            <h:outputText value="#{cap2.name}" />
            </rich:column> 
            </rich:extendedDataTable>
            </h:form> 
            
            </rich:tab> 
            
            <rich:tab id="tab3" label="Third" name="tab3" limitToList="true" reRender="f3" >
            <h:form id="f3">
            This is the third tab
            </h:form> 
            </rich:tab> 
            
            </rich:tabPanel>
            
            
            
            
            
            
            
            
            
            
            

             

             

             

            sample output:

             

            setSelectedTab = tab1
            getCapitals1()getCapitals2()getCapitals1()getCapitals2()
            setSelectedTab = tab2
            getCapitals1()getCapitals1()getCapitals2()getCapitals2()getCapitals1()
            setSelectedTab = tab3
            getCapitals1()getCapitals2()getCapitals1()getCapitals2()

              looks like real issue in extendedDataTable itself.. working fine with simple dataTable.

                feel free to rise an issue but currently we have no plans for 3.x branch.
