      Hi,
      thank you very much for the nice dataModel. It makes working already very simple.


      However I have 2 questions:





      • When I try to eager fetch a property it fails. The same query works when i am displaying it as resultList:




      from Game as game
left join fetch game.firstTeam 
left join fetch game.secondTeam




      java.lang.IllegalArgumentException: org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list [FromElement{explicit,not a collection join,fetch join,fetch non-lazy properties,classAlias=null,role=null,tableName=Team,tableAlias=team1_,origin=Game game0_,colums={game0_.firstTeam_id ,className=org.jockeysoft.better.entity.Team}}] [select count(*) from org.jockeysoft.better.entity.Game as game                            left join fetch game.firstTeam               left join fetch game.secondTeam ]

      • Is it possible (a valid feature request) to make the max-results resolvable at runtime with EL as in:



      <framework:entity-query name="allGamesByNr" ejbql="from Game as game" order="nr" max-results="#{user.maxResultPreference}">




      thank you very much,
