    Doubled call of Bean-Method during rerendering - bug?

    rschoeler Feb 15, 2009 2:34 PM

      Hi folks, I've a problem during AJAX-ing. Excuse if I've used some attributes in the wrong way - but the pdf-doc is sometimes not as clear, that I'am able to understand it 100percently. It's more try&error working.....8-}

      Description:
      I've a rich:comboBox and a rich:dataTable with one rich:column with an a4j:commandLink inside, and rerendering stuff.

      If I change selection of the rich:comboBox, I can see in the logfile that the Bean-Method getResult is called twice. I've tried a lot of ways with a4jregion, ajaxSingle="true",limitToList="true" and other possibilities I've found to avoid this - because this had some side-effects for my implementation.

      This is a bug in my understanding, and has forced me to insert a workaround in my code to ensure, that this doubled calling doesn't do wrong.

      My Questions are:
      Is there a doubled AJAX-Call during rerendering?
      How can I trace such behaviour by myself (with a4j:log) ?
      Is this really a AJAX-bug?

      My Environment:
      - jdk1.6.0_11
      - RF 3.3.0 GA

          Hello,

          The second call is issued by rich:datascroller component. It's not an AJAX bug; that's behavior specific to this component.

              Hi Nick, second is already there although rich:datascroller is removed.

              Therefore the call must come from another component. The page-code has changed a little bit, according to other answers from you - but the main stuff remains the same.

              Could the a4j:commandLink inside rich:column trigger an additional call?
              Maybe only one time - because I have resultsets with more than one row, but the call is only one time.....

              Another similar scenario:
              Although if I only switch selection of rich:comboBox the getResult Method is called twice. There must be a second AJAX-Call from outside, because inside the bean this isn't possible.

              I'm not able to catch the second call....although I've used a4j:log for AJAX-components.

              regards
              roland

                Roland,

                On what phase is the second method call done? Please post new phase tracker log.

                Also can you please add this:

                Thread.dumpStack();
 System.out.println(FacesContext.getCurrentInstance());
                to getResult() method and post output here?

                  Hi Nikolay, both calls are done in the RENDER_RESPONSE(6) Phase.
                  With help of your instructions now I can see, that the second call is done from rich:tooltip.
                  This behaviour is reproducable.

                  I've tried some attributes of rich:tooltip e.g. mode in both variants(ajax/client) and attached(true/false). No effect on the doubled output in the logfile.

                  To fasten up the bugsearch I've marked the three tooltips inside of the page-code

                  regards roland

                    Roland,

                    This looks like a specific issue of MyFaces. Tooltip that is located out of table tries to access model row index in order to match id and this triggers model access. And data table resets its model before rendering view, that's why it calls getResult() method the second time. I guess the changing "for" attribute to "deleteKeylink" will fix the issue:

                    <a4j:commandLink ajaxSingle="true" id="deleteKeylink"
 oncomplete="#{rich:component('deleteKeyPanel')}.show()"
 rendered="#{mappingHandler.selectedIdentifier != null}">
 <h:graphicImage value="/images/delete.gif" style="border:0"/>
 <f:setPropertyActionListener value="#{mappingHandler.selectedIdentifier}"
 target="#{mappingHandler.deletableIdentifier}" />
 </a4j:commandLink>

 <rich:toolTip id="toolDeleteKey"

for="deleteKeylink"

value="#{msgs.tooltip_delete_mappingkey}" mode="client" attached="false"/>

                      Hi Nikolay, thanks for pointing me to a failure of this page. I've corrected this, but the doubled calls are already there. For me this is a bug if combination of rich:comboBox w. a4j:support &rich:dataTable is used - but now I'm aware of this doubled calling, and I will take this in account during implementation.

                      Following facts:
                      1. Only MyFace is affected from doubled calling (Sun RI do only one call)
                      2. It has nothing to do with the tooltips
                      => I've removed all tooltips from this page, but doubled calling is already there
                      3. Coming to this page, do only one call for getResult (my dataTable getter-Method)
                      4. Switching rich:comboBox do always contains doubled call

                      Now it's up to you to decide if this should be handled as bug or not.
                      I would be ensure, that the call to the getter of the tableModel should only be done once - regardless from which JSF-Implementation is used. Don't forget that MyFace is a widely used implementation.

                      regards
                      roland
