    Question about passing an action Listener

      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() {
 }
}


      An this is my xhtml

</div>
</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!

      German.-
