p:ajax + h:selectOneMenu in seam

[dego]

Hi,
First I would like to thank the PF team for the great job that has been done. While trying to replace some richfaces code with PF, I ran into the following issue. As I'm new to PF, I'm probably missing something obvious, so sorry in advance for that.
Basically, I want to ajax-update my model from a h:selectOneMenu change event which locates in a datatable colum.
Seam 2.2.0 GA
Primefaces 1.1

Code: Select all

<h:form prependId="false" id="participants">
    
(...)

    <p:dataTable var="_participant"
    		id="userList"
    		value="#{users.resultList}"
            rendered="#{not empty users.resultList}">

(...)

        <p:column>
            <f:facet name="header">
            	<h:outputText styleClass="columnHeader" value="#{messages['admin.rights']}"/>
            </f:facet>
			<h:selectOneMenu id="status"
					value="#{_participant.status}"
					disabled="#{_participant.status eq 'TEAM'}">
            	<s:selectItems var="_status"
                		value="#{admin.statuss}"
                    	label="#{_status}" /> 
                <s:convertEnum/>
                <p:ajax event="change"
                		process="@this"
                		update="@none"/>
			</h:selectOneMenu>
		</p:column>
	</p:dataTable>

(...)

    </h:form>

Code: Select all

@Name("users")
@Scope(ScopeType.CONVERSATION)
public class Users extends EntityQuery<Contributor>
{
(...)
}

When I change the value in the combo I get the following error in log

Code: Select all

18:27:06,164 WARN  [Component] Cannot create Seam component, scope is not active: users(CONVERSATION)

and the setter method isn't called...

Thanks for help !

forgot to mention that my usecase :

• doesn't occur in a long-running conversation, conversation is temporary.

• worked fine with same code and richfaces tags with the same tag structure :

Code: Select all

<rich:dataTable id="userList" 
        var="_participant"
        value="#{users.resultList}" 
        rendered="#{not empty users.resultList}"
        rowKeyVar="_row">
(...)
    <h:column>
        <f:facet name="header">
            <h:outputText styleClass="columnHeader" value="#{messages['admin.rights']}"/>
        </f:facet>
        <h:selectOneMenu id="status"
                value="#{_participant.status}"
	        disabled="#{_participant.status eq 'TEAM'}">
            <s:selectItems var="_status"
                    value="#{admin.statuss}"
                    label="#{_status}" />
            <s:convertEnum/>
            <a4j:support event="onchange"
                    action="#{users.refresh()}"
                    ajaxSingle="true"
                    reRender="messages">
            </a4j:support>
        </h:selectOneMenu>
    </h:column>
</rich:dataTable>

Cant figure out what is wrong as it seems to be an issue with seam compatibility, problem is PrimeFaces 1.x development is no longer active, this issue should not happen with PrimeFaces 2 but seam does not support it officially.
