    Everything I do I do it wrong...

      Hello!

      I'm almost gave up trying to make something work... :-(

      It looks like nothing works inside repeat tag.
      Being not able to make simpleTogglePanel work I switched to togglePanel and again no luck. It works with switchType="client" but I want AJAX!!! :-)

      P.S. Congrats with 3.1

          Oh. Ok, I see. I can agree with the subject.
          First, move <a4j:log> down, outside of the a4j:outputPanel you are going to re-render in the future.

          What the jsf implementation you use? It should be JSF 1.2 or, at least, facelets to have some code.

            Hi!
            God! Someone alive (and not full with vodka after 3.1 :-))

            Yes I use JBoss 4.2 JSF 1.2
            Log I put after all to see what happens...

            By the way even "client" works the tables I put inside are synchronized... :-(

            All I wanna do is to have a repeater with something "shrinkable" better with ajax, because inside I could have a table with 1000 elements I don't want to get it all at a time, only descriptions... may be I do it wrong in a first place - I'm still thinking in a usual gui manner (with all those threads and asynchrony).

            I tried to look into the code, but got crazy with all those id you calculate dynamically... :-(

            Cheers. (and happy programmers' day :-))

              Yeah!
              I just got the joke.
              You agree with the subject of post, but not with the idea that some components inside <a4j:repeat> doesn't work properly... ;-)
              May it be because I use html and not xhtml and tidy got grazy?

                  Hi!

                  I have a related problem:
                  <a4j:commandButton>-AJAX-requests also fail within <a4j:repeat> (and even within <ui:repeat> and <rich:dataGrid>). Only the repeater component itsself gets refresht (i.e. the collection within the value attribute gets reloaded).

                    did you look at richfaces-demo's samples where the form element inside the iteration components are shown?

                      Yes, and mine <h:form>s also stay outside <ui:repeat>.

                      This does function:

                      <h:form>
 <a4j:commandButton styleClass="cartbutton"
 action="#{cart.add}"
 reRender="cartAmount,cartTotal" />
 </h:form>


                      And those do not function: 
                      <h:form>
 <ui:repeat value="#{products}" var="item">
 <a4j:commandButton styleClass="cartbutton"
 action="#{cart.add}"
 reRender="cartAmount,cartTotal" />
 </ui:repeat>
 </h:form>


                      <h:form>
 <a4j:repeat value="#{products}" var="item">
 <a4j:commandButton styleClass="cartbutton"
 action="#{cart.add}"
 reRender="cartAmount,cartTotal" />
 </a4j:repeat>
 </h:form>


                      <h:form>
 <rich:dataGrid value="#{products}" var="item">
 <a4j:commandButton styleClass="cartbutton"
 action="#{cart.add}"
 reRender="cartAmount,cartTotal" />
 </rich:dataGrid>
 </h:form>


                      Putting the form tags inside the accordant iteration tags does not change the situation.

                        let's understand where is "do not function" starts. When you use <a4j:log /> what it says about re-rendered areas?

                          My #{cart.add} method gets not called and the AJAX4JSF logger spits out:

                            Lets choose a simpliest way. Reduce your code to minimal non working one. And put there all the snippets (do not cut nothing). Also provide precise environment info. So, we'll be able to create an example.

                            Thanks.

                              Ok, three days later and i've got it: Using the org.jboss.seam.annotations.datamodel.DataModel annotation for the iteration model (in my case an java.util.List object) causes a suppression of the action method call! I don't know why. I simply replaced the @DataModel with the @Out annotation within the seam component class providing the collection.

                              May i post the example i've created including all xml descriptors, jar files, classes and pages?

                                  Hi,

                                  after all the problem was not the DataModel annotation i have blamed at first. It was the scope of the component containing the action method.

                                  Here is my (deficient) code:

                                  home.xhtml

                                  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />

<body>
 <h:form>
 <ui:repeat value="#{list}" var="item">
 <a4j:commandButton action="#{bean.increaseNumber}"
 value="Increase Number"
 reRender="number" />
 </ui:repeat>
 </h:form>
 <h:outputText id="number" value="Number: #{bean.number}" />
</body>
</html>


                                  Action component 
                                  package org.domain.IterationExample;

import java.util.ArrayList;
import java.util.List;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.datamodel.DataModel;

@Scope(ScopeType.CONVERSATION)
@Name("bean")
public class IEBean
{
 Integer number;

 @DataModel List<String> list;

 public IEBean()
 {
 number = 0;
 list = new ArrayList<String>();
 list.add("");
 list.add("");
 list.add("");
 }

 public void increaseNumber()
 {
 number += 1;
 }

 public Integer getNumber()
 {
 return number;
 }

 public void setNumber(Integer number)
 {
 this.number = number;
 }
}


                                  So if you switch the scope of the IEBean to SESSION the list gets displayed and you can use the buttons. Otherwise not.

                                  Regards,
                                  Pete

                                    I don't think that repeat component, or a4j:command button know anything about the scope. Nor do they care about difference between session and conversation. I'll look into it.
