[jboss-user] [JBoss Seam] - Question about passing an action Listener

[german.delacruz]

Hi people

I'm very new to seam (Actually, I've using it for 2 weeks). I've read all the documentation I found, I reviewed all the examples.

Nowadays, I'm making my first complete crud. I must say that I've been using tapestry since 2002, then I think my main problem is trying to solve all the problems in the tapestry way.

In my application I've using EJB3, Seam and facelets for the view. I've been using a SFSB with Session scope for the actions. I'm using it with session scope because When I go to any action from the table I lost the last search results (Because the default is a temporal conversation). I can't use a long conversation because in a crud it haven't an end This is my code...


  | package manchot.actions;
  | 
  | import java.util.List;
  | 
  | import javax.ejb.EJB;
  | import javax.ejb.Remove;
  | import javax.ejb.Stateful;
  | 
  | import manchot.model.Person;
  | import manchot.services.PersonService;
  | 
  | 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.Out;
  | import org.jboss.seam.annotations.Scope;
  | import org.jboss.seam.annotations.Unwrap;
  | import org.jboss.seam.annotations.datamodel.DataModel;
  | import org.jboss.seam.annotations.datamodel.DataModelSelection;
  | 
  | @Name("personController")
  | @Stateful
  | @Scope(ScopeType.SESSION)
  | @LoggedIn
  | public class PersonControllerBean implements PersonController {
  | 
  | 	private String searchString;
  | 
  | 	@EJB
  | 	private PersonService personService;
  | 
  | 
  | //	private List<Person> model;
  | 
  | 	@DataModelSelection
  | 	private Person selected;
  | 
  | 	private Person entity;
  | 
  | 	public Person getEntity() {
  | 		return entity;
  | 	}
  | 
  | 	public void setEntity(Person entity) {
  | 		this.entity = entity;
  | 	}
  | 
  | 	public String getSearchString() {
  | 		return searchString;
  | 	}
  | 
  | 
  | 	public Person getSelected() {
  | 		return selected;
  | 	}
  | 
  | 	public void setSearchString(String searchString) {
  | 		this.searchString = searchString;
  | 	}
  | 
  | 	public void setSelected(Person selected) {
  | 		this.selected = selected;
  | 	}
  | 	
  | 	@DataModel("model")
  | 	public List<Person> getModel() {
  | 		return (personService.findByNameLike(searchString));
  | 		//return "personCRUD";
  | 
  | 	}
  | 
  | 	public String select() {
  | 		setEntity(getSelected());
  | 		// setSelected(personService.merge( getSelected()));
  | 		return "personCRUD";
  | 	}
  | 
  | 	public String clearSelected() {
  | 		setEntity(null);
  | 		return "personCRUD";
  | 	}
  | 
  | 	@Destroy
  | 	@Remove
  | 	public void destroy() {
  | 	}
  | }
  |

  | </h:form>
  | </h:panelGroup>
  | </ui:define>
  | </ui:composition>
  | 

Then, I've some questions...


1. What do you think of my code?
2. I can't make a "redirect" with a button from xhtml. When I write a search String I want to redirect to the same page only for reloading the model. How can I make it?
2. My model (I've put and @DataModel in a getter) is never in the session, isn't it? I mean, by now, I don't want to put in in the session, I want to recalculate in any request. Since it's an internal application the DB isn't a problem. But my session size is a problem.
3. I want to make a editor component for this entity. I'm thinking in another facelet templeate this a param to call it with the action to execute. How can I make it?

That's all!

thanks!
