> Multiple calls of a query which has some Relationships with @EmbeddedId fields fails if QuerySQLCache is enabled.
> q = em.createQuery("select l from ListTest l where l.te=:test");
> does create:
> SELECT t0.id, t0.keyA, t0.keyB, t0.keyC, t1.keyA, t1.keyB, t1.keyC, t1.data1, 
>         t1.data2 
>     FROM ListTest t0 LEFT OUTER JOIN TestEntity t1 ON t0.keyA = t1.keyA AND t0.keyB 
>         = t1.keyB AND t0.keyC = t1.keyC 
>     WHERE (t0.keyA = ? AND t0.keyB = ? AND t0.keyC = ?) 
> [params=(int) 1, (int) 2, (int) 3]
> however a second query will create:
> q = em.createQuery("select l from ListTest l where l.te=:test");
> SELECT t0.id, t0.keyA, t0.keyB, t0.keyC, t1.keyA, t1.keyB, t1.keyC, t1.data1, 
>         t1.data2 
>     FROM ListTest t0 LEFT OUTER JOIN TestEntity t1 ON t0.keyA = t1.keyA AND t0.keyB 
>         = t1.keyB AND t0.keyC = t1.keyC 
>     WHERE (t0.keyA = ? AND t0.keyB = ? AND t0.keyC = ?) 
> [params=(int) 3, (int) 2, (int) 3]
> Note the wrong first param !
> (There is some Index filed calculated somewhere in the query and the index Array has [0,0,0] as values, so the 0th position does get updated three times .. the bug should be something with the index i think)
> See attached test-project
