Conversations, Wizards, and Home objects
Hello,
I'm trying to do something pretty straightforward. I want a 2 or 3 screen wizard that will populate and entity object that gets persisted at the end of the wizard. Sounds like a job for a conversation.
I start my conversation in a page.xml file:
<begin-conversation join="true"/>
I've taken my default seam-gen'ed Home object and added annotations to make it conversation-scoped:
@Scope(ScopeType.CONVERSATION)
@Name("custorderHome")
public class CustorderHome extends EntityHome<Custorder> {
@In(create = true)
AddressHome addressHome;
@In(create = true)
UserHome userHome;
...Ok, so now the UI. I have a page like below; the first screen of my wizard:
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:s="http://jboss.com/products/seam/taglib"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:rich="http://richfaces.org/rich"
template="layout/template.xhtml">
<ui:define name="body">
<h:messages globalOnly="true" styleClass="message" id="globalMessages"/>
<h:form id="wiz1" styleClass="edit">
<rich:panel>
<f:facet name="header">New Order Wizard (1 of 3)</f:facet>
<s:decorate id="active" template="layout/display.xhtml">
<ui:define name="label">Order for User</ui:define>
<h:selectOneMenu id="selectUser"
value="#{custorderHome.instance.user}">
<s:selectItems value="#{userList.resultList}" var="user"
label="#{user.name}"
noSelectionLabel="Select User"
hideNoSelectionLabel="1" />
<s:convertEntity/>
</h:selectOneMenu>
</s:decorate>
<p/>
</rich:panel>
<div class="actionButtons">
<s:button view="/Wizard_2.xhtml"
id="next"
value="Next"/>
<s:button view="/home.xhtml"
id="cancel"
value="Cancel"/>
</div>
</h:form>
</ui:define>
</ui:composition>
So far, so good. When run I do get a nice pull-down populated with users as I expect, but... when I hit Next to go to wizard page 2 something doesn't carry over--my User assignment from page 1 isn't visible. In page 1 the pull down is supposed to select and populate a User from the list but on page 2 if I have code like the following I see displayed true, false, (nothing), and (nothing) respectively:
Managed: #{custorderHome.managed}
Wired: #{custorderHome.wired}
Id: #{custorderHome.instance.idcustOrder}
User: #{custorderHome.instance.user.name}
What am I not doing right? I go to the debug.seam screen and can validate that a conversation has been created, a custorderHome object exists in that conversation, but the instance is empty (non-null, but not populated) there too.
Thanks for any help,
Greg
