[jboss-user] [JBoss Seam] - Re: Problems with application-like behaviour project

Tue Oct 31 11:48:00 EST 2006

Waiting for an advice I tried another solution, this does not fail, but does not do what I want: 
I modified the conversation generation in order to provide a conversation id as a commandLink parameter (<f:param name="conversationId" value="#{contextTab.token} />), the conversationId value is passed correctly but ignored by Seam.

  | 	
  | </f:view>
  | </html>
  | 

the ProvaAction.java:

  | import javax.ejb.Remove;
  | import javax.ejb.Stateful;
  | import javax.faces.context.FacesContext;
  | import javax.faces.event.ActionEvent;
  | 
  | import org.jboss.logging.Logger;
  | import org.jboss.seam.annotations.Begin;
  | import org.jboss.seam.annotations.Conversational;

  | import org.jboss.seam.annotations.In;

  | import org.jboss.seam.annotations.Out;
  | import org.jboss.seam.annotations.RequestParameter;
  | import org.jboss.seam.core.Conversation;
  | import org.jboss.seam.core.Manager;
  | 
  | @Stateful
  | @Name("provaAction")
  | @Conversational
  | public class ProvaAction implements Prova {
  | 
  | 	@RequestParameter(value="token")
  | 	private String tok; 
  | 	
  | 	@RequestParameter(value="conversationId")
  | 	private String conv; 
  | 
  | 	@Begin(join=true)
  | 	public String startConversation() {
  | 		FacesContext context = FacesContext.getCurrentInstance();
  | 		String tokz = (String) context.getExternalContext().getRequestParameterMap().get("token");
  | 		Logger.getLogger(this.getClass()).info("TOKEN IS: " + tokz);
  | 		Logger.getLogger(this.getClass()).info("TOKEN FROM REQUEST PARAMETER IS: " + tok);
  | 		Logger.getLogger(this.getClass()).info("CONVERSATION ID PARAMETER IS: " + conv);
  | 
  | 		Logger.getLogger(this.getClass()).info("CONVERSATION IS: " + Conversation.instance().getId());
  | 		return "prova";
  | 	}
  | 
  | 	@End
  | 	public String endConversation() {
  | 		// TODO Auto-generated method stub
  | 		return null;
  | 	}
  | 
  | 	@Remove @Destroy
  | 	public void destroy() {
  | 		// TODO Auto-generated method stub
  | 
  | 	}
  | }
  | 

which produces the following output:

2006-10-31 17:32:46,542 INFO  [it.finservice.organizer.modules.dummy.components.ProvaAction] TOKEN IS: token1
2006-10-31 17:32:46,543 INFO  [it.finservice.organizer.modules.dummy.components.ProvaAction] TOKEN FROM REQUEST PARAMETER IS: token1
2006-10-31 17:32:46,543 INFO  [it.finservice.organizer.modules.dummy.components.ProvaAction] CONVERSATION ID PARAMETER IS: token1
2006-10-31 17:32:46,543 INFO  [it.finservice.organizer.modules.dummy.components.ProvaAction] CONVERSATION IS: 4

Help really appreciated.

Raffaele
