    Converting URL param: javax.faces.Integer fails silently and makes EntityQuery omit where restriction

      Hello,


      (note I'll use -- as a replacement for the equals character)


      entering an URL


      http://localhost:8080/bbstats/club-list.seam?season--2003


      will show me the correct list of clubs for a single season using the following pages.xml entry:



        <page view-id="/club-list.xhtml">
          <param name="season" value="#{seasonHome.id}" converterId="javax.faces.Integer" />
         </page>
      



      As you can see I'm using an integer converter to convert the year string. When changing the URL manually to


      http://localhost:8080/bbstats/club-list.seam?season--20xxx03


      my app will show all clubs because that somehow kills the where clause of the EJBQL in EntityQuery:


      Hibernate:



          select
              club3_.id as id1487_,
              club3_.color_name as color5_1490_,
              club3_.name as name1490_,
              club3_.shorthand as shorthand1490_,
              club3_.website_url as website3_1490_ 
          from
              Rosters roster0_ 
          left outer join
              Seasons season1_ 
                  on roster0_.season_start_year=season1_.start_year 
          left outer join
              Teams team2_ 
                  on roster0_.club_id=team2_.club_id 
                  and roster0_.ordinal_nbr=team2_.ordinal_nbr 
                  and roster0_.teamtype_code=team2_.teamtype_code 
          left outer join
              Clubs club3_ 
                  on team2_.club_id=club3_.id 
          left outer join
              Contacts club3_1_ 
                  on club3_.id=club3_1_.id 
          group by
              club3_.id 
          order by
              club3_.shorthand,
              club3_.name




           
      As you can see, no where clause. I then found this in my logs:


      22.10.2010 17:01:12 com.sun.faces.lifecycle.RenderResponsePhase execute
      INFO: WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
      sourceId=null[severity=(ERROR 2), summary=(j_id0: '20xxx03' must be a number consisting of one or more digits.), detail=(j_id0: '20xxx03' must be a number between -2147483648 and 2147483647 Example: 9346)]



      I'd expect a failing converter to display an error and not to continue silently, resulting in a swallowed where clause which actually causes the used query to execute without restrictions, showing all DB entities.


      How do I fix this? What's the best practice here?
