Major Description
OpenJPAEntityManager oem = OpenJPAPersistence.cast(em);
OpenJPAQuery query = oem.createQuery("openjpa.MethodQL", "de.logentis.openjpa.LogentisMethodQL.blabla");
query.setResultClass(DP_PLZ_DA.class);
query.setParameter(1, "Fred").setParameter(2, "Lucas");
This results of an empty parameter Map in the LogentisMethodQL.blabla() method.
Even worse, when doing parameter passing as stated in the docs Chapter 9 / 5:
query.setParameter("first", "Fred").setParameter("last", "Lucas");
There is an exception thrown.
In fact MethodQL is completely broken when it comes to parameters at this point.
