    Problems with rich:orderedList

    Kashif Nazar Newbie

      Hello,

      I am getting this exception error.

      sourceId=category_order_form:videosOrderingList[severity=(ERROR 2), summary=("Component category_order_form:videosOrderingList has invalid value expression eu.digitania.admingui.beans.Category@ca9a2d"), detail=("Component category_order_form:videosOrderingList has invalid value expression eu.digitania.admingui.beans.Category@ca9a2d")]


      This is how I am coding it

      <rich:orderingList id="videosOrderingList"
       value="#{categoryBean.videoCategories}" var="category" converter="categoryConverter" selection="#{categoryBean.selectedVideoCategories}">
       <rich:column>
       <h:outputText value="#{category.name}"></h:outputText>
       </rich:column>
      </rich:orderingList>


      where categoryBean.videoCategories is mapped to a List

      This is my converter

      public class CategoryConverter implements Converter
      {
      
       @Override
       public Object getAsObject(FacesContext context, UIComponent component, String name)
       {
       Category category = new Category();
       category.setName(name);
       return category;
       }
      
       @Override
       public String getAsString(FacesContext context, UIComponent component, Object object)
       {
       Category category = (Category) object;
       return category.getName();
       }
      
      }


      What might be the problem.

          Are equals and hashCode properly defined for Category class?

            No, what logic can I used for these two overloads. Any example?

              richfaces-demo contains the code. checkout sources from svn to explore the case locally.

                correction Overrides

                  I overrode the two functions like this.

                  public boolean equals(Object object)
                   {
                   if (object instanceof Category)
                   {
                   Category category = (Category) object;
                   try
                   {
                   if (this.categoryId.equals(category.getCategoryId()))
                   {
                   return true;
                   }
                   }
                   catch (NullPointerException e)
                   {
                   e.printStackTrace();
                   }
                   }
                   return false;
                   }
                  
                   public int hashCode()
                   {
                   if(this.getCategoryId()!=null)
                   {
                   return this.getCategoryId().hashCode();
                   }
                   return (int)(Math.random()+1*10000);
                   }
                  


                  but the problem is still there.

                    Eclipse has equals/hashCode generation feature out of the box. Check if your IDE is equipped with one.

                      This time I generated the overrides using eclipse.

                      These are the functions

                      @Override
                       public int hashCode()
                       {
                       final int prime = 31;
                       int result = 1;
                       result = prime * result + ((categoryId == null) ? 0 : categoryId.hashCode());
                       result = prime * result + ((contenttypeId == null) ? 0 : contenttypeId.hashCode());
                       result = prime * result + ((name == null) ? 0 : name.hashCode());
                       result = prime * result + ((sequenceNumber == null) ? 0 : sequenceNumber.hashCode());
                       return result;
                       }
                      
                       @Override
                       public boolean equals(Object obj)
                       {
                       if (this == obj)
                       return true;
                       if (obj == null)
                       return false;
                       if (getClass() != obj.getClass())
                       return false;
                       Category other = (Category) obj;
                       if (categoryId == null)
                       {
                       if (other.categoryId != null)
                       return false;
                       }
                       else if (!categoryId.equals(other.categoryId))
                       return false;
                       if (contenttypeId == null)
                       {
                       if (other.contenttypeId != null)
                       return false;
                       }
                       else if (!contenttypeId.equals(other.contenttypeId))
                       return false;
                       if (name == null)
                       {
                       if (other.name != null)
                       return false;
                       }
                       else if (!name.equals(other.name))
                       return false;
                       if (sequenceNumber == null)
                       {
                       if (other.sequenceNumber != null)
                       return false;
                       }
                       else if (!sequenceNumber.equals(other.sequenceNumber))
                       return false;
                       return true;
                       }


                      But I still face this message

                        Ok, post code for categoryBean please.

                              This may also happen if data changes between requests. Make sure that DAO satisfies this requirement. What is bean scope?

                                  bean scope is request. The DAO will always return the same results
