[jboss-user] [JBoss Seam] - Re: problem with conversations

[Kruno]

I was a bit lost in your example:
here is on of mine :
pages.xml:


  | 
  | <page view-id="/page.jsp" >
  | 			<begin-conversation join="true"/>
  | 	</page>
  | 

RegisterAction

  | package orka.test;
  | 
  | import javax.ejb.Remove;
  | import javax.ejb.Stateful;
  | import javax.persistence.EntityManager;
  | import javax.persistence.PersistenceContext;
  | 
  | import org.jboss.seam.ScopeType;
  | import org.jboss.seam.annotations.Destroy;
  | import org.jboss.seam.annotations.In;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.Scope;
  | 
  | @Stateful
  | @Scope(ScopeType.CONVERSATION)
  | @Name("register")
  | public class RegisterAction implements Register  {
  | 
  | 	@PersistenceContext
  | 	private EntityManager em;
  | 	
  | 	@In
  | 	User user;
  | 	
  | 	
  | 	public String reg(){
  | 		System.err.println(user.getName());
  | 		// check for errors
  | 		// then persist
  | 		//em.persist(user);
  | 		
  | 		return "ok";
  | 		
  | 	}
  | 	@Remove @Destroy
  | 	public void destroy(){
  | 		
  | 	}
  | 	
  | }
  | 

user class I belive that this is much better way if you divide data form actions 

  | package orka.test;
  | 
  | import org.jboss.seam.ScopeType;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.Scope;
  | 
  | // make him an entity so you can persist him
  | @Name("user")
  | @Scope(ScopeType.CONVERSATION)
  | public class User {
  | 
  | 	private String name;
  | 
  | 	public String getName() {
  | 		return name;
  | 	}
  | 
  | 	public void setName(String name) {
  | 		this.name = name;
  | 	}
  | 	
  | 	
  | 	
  | 	
  | }
  | 
 and jsp page 

  | 
  | <%@ page contentType="text/html; charset=UTF-8" %>
  | <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
  | <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
  | <%@ taglib uri="http://jboss.com/products/seam/taglib" prefix="s"%>
  | 
  | 
  | <f:view>
  | <h:form id="forma">
  | 
  | <h:inputText value="#{user.name}"></h:inputText>
  | 
  | <h:commandButton action="#{register.reg}" value="register" />
  | 
  | 
  | 
  | </h:form>
  | </f:view>
  | 

every time you come to page it will be a new conversation because user entity is conversation scope and it is empty, but when you submit it is not new conversation. I think that is what you want
