    Setting page parameter isn't working

      Hi.


      I'm having troubles with integeration tests for my Seam EAR application (the appliction's skeleton is generated via seam-gen)


      pages.xml


          <page view-id="/category.xhtml" action="#{categoryAction.listBooksByCategoryName}">
        <param name="name" value="#{category.name}" required="true"/>
    </page>


      Category.java


      @Stateless
@Name("categoryAction")
public class CategoryAction implements ICategory {

    @PersistenceContext
    private EntityManager entityManager;

    @Out(scope = ScopeType.EVENT, required = true)
    private List listOfBooks;

    private Category category;
    @TransactionAttribute(TransactionAttributeType.SUPPORTS)
    public String listBooksByCategoryName() {
        listOfBooks = entityManager.createNamedQuery("findBooksByCategoryName").setParameter("name", category.getName()).
                getResultList();
        return StringConstants.SUCCESS;
    }
}


      Category.java


      @Entity
@Name("category")
@BatchSize(size = 5)
@NamedQueries({
@NamedQuery(name = "findBooksByCategoryName",
        query = "select book from Category category join category.books book where category.name = :name")
        })
public class Category implements Serializable {


      CategoryTest.java


      public class CategoryTest extends SeamTest {
    @Test
    public void listBooksByCategoryTest() throws Exception {

        new NonFacesRequest("/category.xhtml") {
            @Override
            protected void beforeRequest() {
                setParameter("name", "Java");
            }

            @Override
            protected void renderResponse() throws Exception {
                List list = (List) Contexts.getEventContext().get("listOfBooks");
                assert list != null;
            }
        }.run();

    }
}


      But upon running the test I got a NullPointerException from category.getName() from CategoryAction class.
      It seems that an instane of Category class doesn't get created.
      Any ideas?


      One more thing:


      Is it possible to have:


      private String category;
      instead of:


      private Category category;


      in CategoryAction.java?


      (Ubuntu 7.10 and Seam 2.0.0GA)


      Thanks for help and time.

          try this:


          <param name="name" value="#{categoryAction.categoryName}" required="true"/>



          on CategoryAction use this:


          private String categoryName;



          u should also consider passing the the category Id (if you have one..)

            I tried this:


                <page view-id="/category.xhtml" action="#{categoryAction.listBooksByCategoryName}">
        <param name="name" value="#{categoryAction.categoryName}" required="true"/>
    </page>



            And CategoryAction.java


            private String categoryName;


            But I got the same error, no value doesn't its value set.


            What about annotating categoryName as:



            @RequestParameter
private String categoryName;



            This time the value is set but I got this exception:

              I switched the application to a WAR (POJOs not EJB3), the page action and page parameter is working without any problem, even without @RequestParameter.


              Any help will be great.
