scope is not active at ajax request

[jurijlender]

Hi,

when clicking an ajax commandButton, i want a bean property to be populated with the current value of an iteration. The setter method is called, but unfortunately the value of the property remains null.

view:
<table>
<a:repeat value="#{userBean.resultList}" var="_user">
<tr>
<td><h:outputText value="#{_user.name}" /></td>
<td><a:commandButton ajaxSingle="true" value="Select" reRender="userDetail">
<f:setPropertyActionListener value="#{_user}" target="#{userBean.selectedUser}" />
<s:conversationId />
</a:commandButton></td>
</tr>
</a:repeat>
</table>


*page.xml:

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://jboss.com/products/seam/pages"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.2.xsd">
        <begin-conversation join="true" flush-mode="auto"/>
</page>


action-bean:

@Name("userBean")
@Scope(ScopeType.CONVERSATION)
public class UserBean {
       
        @In(create = true, required = false) EntityManager entityManager;
        @Logger Log log;
       
        private User selectedUser;

        [...]
}



the interesting part is, that i get the following warning in my console:

14:22:53,695 WARN  [org.jboss.seam.Component] Cannot create Seam component, scope is not active: userBean(CONVERSATION)


How is that possible? i have already searched for equivalent posts, also i have restarted the application on my server (using jboss 6 M2)

The root element for pages.xml is <pages> not <page>.  Another item is that the view doesn't look like it's in a form, you may have removed it to post here, but something to check into.  Let us know.

Hi, thanks for your reply.

Somehow it is working now. Although i don't know why.
If i find out, i'll post what went wrong.

I have been digging a similar problem for a week. Your somehow just did not happened to me.  I narrowed done to a bare simple test --

As long as I have a4j:repeat in my form (even with an empty body), all my ajax actions on the form produce this. Most time the action is actually executed without a problem.  But I cannot get anything working inside the repeat loop.

If you have a clue how this is resolved, please do let me know.
