    Outjection in subclass of EntityQuery<T> generated by seam-gen

    Milind S Newbie

      Hi,


      I am using seam-gen generated code which is very simple class as below.


      import org.jboss.seam.annotations.Name;
      import org.jboss.seam.annotations.Out;
      import org.jboss.seam.annotations.Scope;
      import org.jboss.seam.annotations.intercept.BypassInterceptors;
      import org.jboss.seam.framework.EntityQuery;
      import java.util.Arrays;
      
      @Name("productList")
      @Scope(ScopeType.SESSION)
      public class ProductList extends EntityQuery<Product> {
      
           private static final String EJBQL = "select product from Product product";
      
           private static final String[] RESTRICTIONS = {
                     "lower(product.network) like lower(concat(#{productList.product.id},'%'))",
                     "lower(product.source) like lower(concat(#{productList.product.source},'%'))",
                     "lower(product.zone) like lower(concat(#{productList.product.zone},'%'))",};
                
           private product product;
           
           public productList() {
                setEjbql(EJBQL);
                setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
                setMaxResults(25);
           }
      
           public product getproduct() {
                return product;
           }
           
      }
      



      I am displaying the list of products in a xhtml file generated by seam in table format in 7 columns which has around 30 products.


      What I am observing is the getProduct() method is called hundreds of times.


      Question - Why getProduct() method is called hundreds of times?


      I tried to use @BypassInterceptor for getProduct() method but still it is getting called hundreds of time.


      Then I tried to outject variable product by using @Out. It gave me exception org.jboss.seam.RequiredException: @Out attribute requires non-null value.


      After that I tried to use @Out for getProduct() method instead of product variable. I changed the method as below


           
      @Out (scope=ScopeType.SESSION)
      public Product getproduct() {
           if (product == null) {
                 product = new product();
           }
           return product;
      }
      


      Now the exception is gone but getProduct() method is getting called for hundreds of times.


      Question - Is outjection work in EntityQuery? or it only work in beans, SLSB, SFSB?


      Can somebody help me to resolve this issue?
