    Testing a4j with JSFUnit

    marti

       

      I have 2 selectOneMenu. the second one becomes acrtive and gets <option>s after user select any option from first one.

      the fulfillment of options is being done by a4j.

      here is the code:

       

      <h:selectOneMenu  required="true" rendered="#{selectType!='' and selectType != null and  selectType =='menu' }" id="orderForm"
      value="#{controller.printProductSpecificationsFacesProxy[rs]}" disabled="#{! controller.canSelectSpecification(rs)}">
      <f:selectItem itemLabel="#{messages.message('selectOption')}" itemValue="" />
      <f:selectItems id="#{rsOption}" value="#{selectItems}" />
      <a4j:support  event="onchange" limitToList="false"  reRender="outputPanel"  ajaxSingle="true" eventsQueue="queue" ignoreDupResponses="true" />
      </h:selectOneMenu>

       

      When  i select any option from first one, i output the page to a file to see  if ajax fills the options or not. i can see that second selectOneMenu  still has one option and not filled.

       

      i use following method to work with SelectOneMenu:

      select = (HtmlSelect) client.getElement("orderForm");
      select.getOptionByValue("1").setSelected(true);

       

      what should i do to get ajax working.

      thanks.

          I assume all this works in the browser?

           

          Are you saying that the selectOneMenu, "orderForm" only has one item in it?

           

          I'm not an a4j expert, but I'd play around with some of the attributes.  Do you really need to use the eventsQueue?

           

          How are you outputting to a file?

            selectOneMenu has one option initally but after selecting one of the options from first one, second one generates its options using this line:

            <a4j:support  event="onchange" limitToList="false"   reRender="outputPanel"  ajaxSingle="true" eventsQueue="queue"  ignoreDupResponses="true" />

            I only need to get these updates.

            it seems that select.getOptionByValue("1").setSelected(true) doent produce ajax which is inside <h:selectOneMenu> tag.

              Stan, I've been helping Marti get JSFUnit running on his app for a few days now (hampered by time difference a little) and we've made pretty good progress. But, I'm not quite sure why his ajax isn't working on this particular case. I want to go write a small demo page to test it out myself and see if I can track it down. Hopefully I can get around to it today. (But, I really should be doing my own work )

              My initial thought is that the onchange event isn't firing. That being said we could test that I guess.

               

              For the record though, the scenario (as best I can tell as I don't actually have the source just parts of it). Is that the page contains a selectOneMenu that when a value is selected causes a second selectOneMenu to now contain dependent options which then populates a 3rd and the 3rd populates a 4th. So initially the 1st selectOneMenu is the only one with selectable options and once a value is selected the panel is rerendered by ajax and the 2nd selectOneMenu now contains selectable values and so on and so on. Marti, please correct me if I'm wrong

               

              Marti,

              How bout we put some logging in your method that generates the options and see if it is being executed. Let's work out how far we are getting in this process. We can then start narrowing down where we should start looking.

                Hey Tim

                thanks for joining...

                this is the error i get

                 

                elementName=[option] attributeName=[value] attributeValue=[1]

                com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[option] attributeName=[value] attributeValue=[1]

                 

                now I'm sure

                select.getOptionByValue("101").setSelected(true);

                does not call

                <a4j:support event="onclick"

                 

                yes it's a good idea to put log.

                  O yes the senario is totally correct.

                    It doesn't need to fire the onclick event, it needs to fire the onchange event. At least that's what I see in your a4j tag

                     

                    "<a4j:support  event="onchange .../>"

                     

                    and the setSelected(true) *should* fire that event.

                      yes i copied wrong <a4j

                      yes it should work with <a4j:support event="onchange" and fire it.

                        OK, so I went and wrote a simple test. This works for me. Marti, can you copy this test to your source and run it and see if it runs for you. If it does then it narrows down where the problem lies. Can you also post your entire source for your test and xhtml including the xhtml that is generating these dynamic selectOneMenus.

                         

                        The code below is very primitive and poorly written but it was just to prove a point So, please don't think this is how I normally write code LOL.

                          Hey Tim

                          can you send me required jars for class AjaxTest. what are the imports for that class?

                          thanks.

                            Marti,

                             

                            The jars you are using for your current testing should be fine. I purposfully made the test use as little as possible. The only thing you might want to do is remove the line

                            xmlns:rich="http://richfaces.org/rich"
                            

                            from the xhtml.

                             

                            If you are getting ClassNotFound exceptions then please post them here so we can work it out. But, I'm pretty sure I have no references to any special libs in that example.

                             

                            So yeah, if you can't get this test running then post the errors maybe it will help us find your underlying problem.

                              I'm getting red lines under @Name, @Scope lines and also under AbstractSeamComponent.

                              When I import jboss.Seam.* lib in order to make annotations understandable, in that case i'm getting server 500 error when I run the test in browser.

                              I deleted that jar and now test is working.

                              what makes that conflict?

                                Bleh, I forgot to remove the

                                extends AbstractSeamComponent

                                 

                                that's just my internal superclass for all our Seam beans. Nothing fancy in there.

                                 

                                The @Name and @Scope are plain Seam annotations if you are getting a 500 error then check your server log, or make sure you are typing in the right url.

                                  With regards to the comment about the Jar.

                                   

                                  What Jar did you delete and from where did you delete it?

                                  So, the example test is running now? Does it succeed or fail?

                                    OK, I deleted jboss-seam.jar from WEB-INF/lib

                                    I commented 2 annotations, because there is no jboss-seam.jar anymore. i run the test and get this error.
