[jboss-user] [JBoss Seam] - Event scoped component accessing Conversion scope

[quilleashm]

I have a search component which is event scoped.  Itself it just has four properties which are bound to four input fields in my JSF page.

It extends a generic search component which has a hibernate session which is injected by the @In( create = true ) from the ManagedHibernateSession component.  This generic component has bindings to a couple of the controls on the JSF page (grid/parameter panel etc).

The search renders fine when it is visited the first time, including some db queries to get some meta-information.   On clicking the search button which posts back the @In injection of the Session fails because the bijection gets fired when binding the UI components to the search object.  This happens during the restore view phase when the conversation scope is not available and therefore neither is the hibernate session.

I get the feeling I'm just not using it right but I'm not sure why.  Is injecting conversation scoped components into event scoped components something that shouldn't/can't be done?  Or do I have my components badly designed.

I've posted the highlights of the classes here..

The component


  | @Name( "elementSearch" )
  | @Scope( ScopeType.EVENT )
  | public class ElementSearch extends SparkSearch
  | {
  |     // control value bindings
  |     private String eltName;
  |     private Integer elementSet;
  |     private Integer country;
  |     private String eltDigits;
  | 
  |     public String getEltName()
  |     {
  |         return eltName;
  |     }
  | 
  |     // ... more getters/setters here
  | 


  | public abstract class SparkSearch
  | {
  |     private UIData dataGrid;
  |     private HtmlPanelGrid parameterGrid;
  | 
  |     @In( create = true )
  |     private Session referenceSession;
  | 
  |     @In( required = true )
  |     private SessionFactory referenceSessionFactory;
  | 
  |     public HtmlPanelGrid getParameterGrid()
  |     {
  |         return parameterGrid;
  |     }
  | 
  |     public void setParameterGrid( HtmlPanelGrid parameterGrid )
  |     {
  |         // this gets called during the restore-view phase at which point the bijection fails on the referenceSession
  |         this.parameterGrid = parameterGrid;
  |     }
  | 
  |     // .. more getters/setters here + action methods
  | 

Any comments appreciated.

Cheers.

Mike.
