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() {
| }
| }

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!
