[jboss-user] [JBoss Seam] - create method not found + @Factory

[Basel]

Hello,

I am trying to cerate a new entry, entity bean, using three pages with the help of jBPM similar to the example illustrated  in jbossworld-seam-lab.zip file. These three pages are going to be used in a RESTful application that follows the blog example.

So, I have a data entry page called newentry.jsf, similar to the bolg example, that has a reference to a variable created with the help of the @Factory annotation. In that page the variable is referenced just like any bean:

  | <h:inputText id="title" value="#{newEntry.title}"
  |     size="70" maxlength="70" required="true"/>
  | 

The method that creates the variable is in a stateful session bean, to take advantage of jBPM pageflow:

  | @Stateful
  | @Name("postAction")
  | public class PostAction implements PostActionInterface{
  | 	
  | 	@In(create=true)
  | 	private Category category;
  | 	
  | 	//@In(create=false, value="newEntry")
  | 	@In(create=false)
  | 	private Entry entry;
  | 	
  | 	@Factory("newEntry")
  | 	public void createNewEntry(){
  | 		entry = new Entry(category);
  | 	}
  | 	
  | 	@Logger
  | 	private Log log;
  | 	
  | 	//@Begin(pageflow="new-entry", join=true)
  | 	@Begin(pageflow="new-entry")
  | 	public void startPost(){
  | 		log.info("Starting to create a new post");
  | 	}
  | 	
  | 	@Remove @Destroy
  | 	public void destroy(){}
  | }
  | 

As you might have noticed, there is a page event in pages.xml that is supposed to call startPost() method in order to start a new conversation:

  | <page view-id="/newentry.jsf" action="#{postAction.startPost}"/>
  | 

Unfortunately, when I try to access the newentry.jsf page I get the following stacktrace:

I forgot to mention that the entity bean entry is only annotated with @Entity. What did I do worng?
