    Rich Faces issue with IE7

    Praveen Mohan Mohanan Newbie

      Hi...All,

      We are using Exadle Studio 4.0 (Ajax)

      We are getting an error message (Line : 375 Error : Object expected)
      in one of the screen when the user hits a button :
      <input id="_idJsp0:clientcode" name="_idJsp0:clientcode" type="text" value="648" maxlength="5" size="5" class="FrmNormalType" tabindex="1" onblur="A4J.AJAX.Submit('_idJsp0:reg1','_idJsp0',event,{'eventsQueue':'clicodequeue','parameters':{'_idJsp0:cn':'_idJsp0:cn'} ,'actionUrl':'/eFiling/jsp/forms/searchHR.jsf','ignoreDupResponses':true} )" />



      When I debugged it using MS debugger , Here is the line that I get error

      <input id="_idJsp0:_idJsp25" name="_idJsp0:_idJsp25" type="submit" value=" &lt;&lt; Search &gt;&gt;" onclick="if(typeof window.clearFormHiddenParams__idJsp0!='undefined'){clearFormHiddenParams__idJsp0('_idJsp0');}if(typeof window.getScrolling!='undefined'){oamSetHiddenInput('_idJsp0','autoScroll',getScrolling());}" class="FormSubmit" />


      This works fine in IE 6 , Firefox etc. and was also working in the earlier version on IE 7.

      Can you please tell me is there a know issue with Ajax & IE7 ?

      Regards,

      P

          I am experiencing like problems and have found that this happens with IE7 hotfix 947864. All is well if I remove this update. I have tried to disable the native XMLHttp in my browser to no avail.

          Do we have any other options?

          I'm using 3.1.5GA.

            did you able to probide sample for us?

            I use IE 7 with all updates and has no such errors in my environment.

              I will create a small project tonight to demonstrate this bug. I use Firefox at the house, but we have to use IE for work. In the meantime, I can confirm that the action method is called and that I see no javascript errors. Page simply refuses to navigate.

                Do you trying to navigate using ajax components?

                Are you sure you do not forget to define the navigation case as redirect? You have to do it using navigation after ajax request. And in general why do you need ajax if you should perform navigation?

                  Here's the code. I'm using the jars from the 3.1.5 demo download with myfaces 1.1.5 and tomahawk 1.1.6. I could always send you the war file if you request. I deployed this to JBoss 4.0.5GA and OC4J 10. I tested against Firefox and all works well. I test with IE6 and all is well. I test with a fully patched IE7 and can not move beyond the people page. I remove the mentioned patch and it works just fine.

                    Here is the code that was written for a button :
                    <h:commandButton action="#{hrDataViewBean.searchHr}"
                    disabled="#{navigatorBean.userRole!='CLIENTUSER' && navigatorBean.userRole!='MATRIXUSER'}"
                    type="submit" styleClass="FormSubmit" value=" << Search >>" />


                    This is how it looks in the HTML when rendered:

                    <input id="_idJsp0:_idJsp25" name="_idJsp0:_idJsp25" type="submit" value="&lt;&lt; Search &gt;&gt;" onclick="if(typeof window.clearFormHiddenParams__idJsp0!='undefined'){clearFormHiddenParams__idJsp0('_idJsp0');}if(typeof window.getScrolling!='undefined'){oamSetHiddenInput('_idJsp0','autoScroll',getScrolling());}" class="FormSubmit" />


                    And Here is the code that throws the Javascript error :
                    <!-- MYFACES JAVASCRIPT -->

                    <!--

                    function getScrolling()
                    {
                    var x = 0; var y = 0;if (self.pageXOffset || self.pageYOffset)
                    {
                    x = self.pageXOffset;
                    y = self.pageYOffset;
                    }
                    else if ((document.documentElement && document.documentElement.scrollLeft)||(document.documentElement && document.documentElement.scrollTop))
                    {
                    x = document.documentElement.scrollLeft;
                    y = document.documentElement.scrollTop;
                    }
                    else if (document.body)
                    {

                    return x + "," + y;

                      Not sure why the JS is not visible :


                      function getScrolling()

                      var x = 0; var y = 0;if (self.pageXOffset || self.pageYOffset)

                        One more time. add

                        <redirect/>
                        tag to your navigation case.

                        Create jira issue and attach the war if not helps.

                          Fair enough, but what if I'm request scope and not session scope? I have an existing code base where the previous developers chose to make everything request scope ... afraid to use session I suppose ... and use the myfaces t:saveState tag everywhere. I'd love to make everything session based with redirect in the navigation, but that's a huge change with the code base.

                          However, I'm more than happy to go forward with changing it all to session scope, removing the saveState tags, and using the redirect markup in my navigation xml if this is the only thing that is breaking a4j with the IE7 update I mentioned.

                          It would also be nice to have an explanation on why the hotfix breaks the ajax functionality. Ideally, we would simply use Firefox and be done with it, but those decisions were made before me and won't likely change any time soon.

                          'One more time', thanks again for your help. Support is a rough job and I understand that the fuse is short at times.

                            If this isn't too complex for you please send me sample war instead of pasting the code there.

                                  Well, with the change in my java code, I don't even need to use the t:saveState tag at all.

                                  I think I will still make the argument for making the controllers session based just so that they don't have to be recreated between requests.

                                  “Had a slight weapons malfunction, but everything's perfectly alright now. We're fine, we're all fine, here, now, thank you. How are you?�

                                    Hi budoray,

                                    Did you find a fix for your request beans??

                                    I have a similar issue and can't change my request beans into session beans. I have a transactional site and that would not be very good for memory management.

                                    Fair enough, but what if I'm request scope and not session scope? I have an existing code base where the previous developers chose to make everything request scope ... afraid to use session I suppose ... and use the myfaces t:saveState tag everywhere. I'd love to make everything session based with redirect in the navigation, but that's a huge change with the code base.


                                    Thanks
                                    Phil
