injection problem with entityhome

[aozoren]

hi - this seems to be a 2.1.2 problem..

i try to inject/use EventHome as below but it does not get injected.. i can verify that EventHome does get created.. any idea on what is going on? thanks.

        @In
        private EventHome eventHome;
       
    public EventTagList()
    {
        setEjbql("select eventTag from EventTag eventTag where eventTag.event.id = " + eventHome.getInstance().getId());
    }

update.. EventHome in question is plain EntityHome derived 'home'.. Seam's 'entityManager' is injected fine..

[aozoren]

eventHome is available on the page so the page renders if i don't include eventTagList.. eventHome is always null in eventTagList code..

@Name("eventHome")
@Scope(ScopeType.SESSION)
public class EventHome extends EntityHome<Event>
{
    @RequestParameter Long eventId;

    @Override
    public Object getId()
    {
        if (eventId == null)
        {
            return super.getId();
        }
        else
        {
            return eventId;
        }
    }

    @Override @Begin(join=true)
    public void create() 
    {
        super.create();
        getInstance().setCreateOn(new Date());
        System.out.println("*** event begun");
    }
}

@Name("eventTagList")
public class EventTagList extends EntityQuery<EventTag>
{
     @Logger
     Log log;
     
     @In
     private EventHome eventHome;
     
    public EventTagList()
    {
         log.info(eventHome);
         
        setEjbql("select eventTag from EventTag eventTag"); // where eventTag.event.id = " + eventHome.getInstance().getId());
    }
}

event.xhtml..

    <h:form id="eventForm">

        <rich:panel>
            <f:facet name="header">event</f:facet>

            <s:decorate template="layout/edit.xhtml">
                <ui:define name="label">description</ui:define>
                <h:inputText required="true"
                             value="#{eventHome.instance.description}"/>
            </s:decorate>

            <div style="clear:both"/>

        </rich:panel>

        <div class="actionButtons">
            <h:commandButton id="save"
                          value="Save"
                         action="#{eventHome.persist}"
                       rendered="#{!eventHome.managed}"/>
            <h:commandButton id="update"
                          value="Save"
                         action="#{eventHome.update}"
                       rendered="#{eventHome.managed}"/>
            <h:commandButton id="delete"
                          value="Delete"
                         action="#{eventHome.remove}"
                      immediate="true"
                       rendered="#{eventHome.managed}"/>
            <s:button propagation="end"
                               id="cancel"
                            value="Cancel"
                             view="/eventList.xhtml"/>
        </div>

    </h:form>

     <s:div rendered="#{eventHome.managed}">
    <rich:panel>
        <f:facet name="header">eventTagList</f:facet>

        <div class="results">

            <h:outputText value="No eventTag exists"
                       rendered="#{empty eventTagList.resultList}"/>

            <h:dataTable id="eventTagList" var="eventTag"
                      value="#{eventTagList.resultList}"
                   rendered="#{not empty eventTagList.resultList}">
                <h:column>
                    <f:facet name="header">tag</f:facet>
                    #{eventTag.tag}
                </h:column>
                <h:column>
                    <f:facet name="header">tag</f:facet>
                    #{eventTag.value}
                </h:column>
            </h:dataTable>

        </div>

Injection is not availbile in the constructor (How do you expect seam to inject something before the object is created?).

Put the login in an @Create method instead.

Stuart -

Your comment made me realize that wizard created a constructor not the usual getEjbql as in previous releases..

Thanks, -a
