Pageflow executed before the model values are applied
I am seeing a problem in that the pageflow seems to be executed before the model values are
applied, is this a bug or is it a problem with my configuration.
//the page is first requested
14:03:23,365 INFO [DocumentRegisterEntryBean] Start called
14:03:23,380 INFO [DocumentRegisterEntryBean] getType null
14:03:23,402 INFO [DocumentRegisterEntryBean] getType null
//the form is submitted, getType is called by the pageflow before the set method.
14:03:27,340 INFO [DocumentRegisterEntryBean] getType null
14:03:27,341 INFO [DocumentRegisterEntryBean] setType register

The form
<h:form>
<h:outputText value="#{messages.itIsA}"/>
<h:selectOneRadio value="#{documentRegisterEntry.type}">
<f:selectItem
itemValue="document" itemLabel="#{messages.document}"/>
<f:selectItem
itemValue="register" itemLabel="#{messages.register}"/>
</h:selectOneRadio>
<h:commandButton action="next" value="#{messages.next}" />
</h:form>
The code
@Scope(SESSION)
@Name("documentRegisterEntry")
public class DocumentRegisterEntryBean implements Serializable, DocumentRegisterEntry
{
private String type;
@Logger
private Log logger;
@In(create=true)
private Document document;
@PersistenceContext()//type=EXTENDED)
private EntityManager em;
@Create
//@Begin()
@Begin(pageflow="documentRegisterEntry")
public void start()
{
logger.info("Start called");
}
@End
// @Transactional()
public void save()
{
logger.info("Save called");
}
@Remove @Destroy
public void destroy()
{
logger.info("Destroy called");
}
public Document getDocument()
{
logger.info("getDocument "+document);
return document;
}
public void setDocument(Document document)
{
logger.info("setDocument "+document);
this.document = document;
}
public String getType()
{
logger.info("getType "+type);
return type;
}
public void setType(String type)
{
logger.info("setType "+type);
this.type = type;
}
The pageflow
<?xml version="1.0"?>
<pageflow-definition name="documentRegisterEntry">
<start-page name="type" view-id="/documentOrRegister.xhtml">
</start-page>
<!-- action is never triggered -->
<page name="register" view-id="/register.xhtml">
<page name="document" view-id="/document.xhtml">
