Custom SQL for FilterExpressionCheck

[white3km]

I have an entity that uses the JPQLPredicateGenerator annotation for one of its fields. I'm trying to create a FilterExpression check and I was wondering if there's a way to use the same logic for the expression check. Right now I can get the query to run but the where clause is not the desired clause so we get no results. Basically I need the custom expression that is used in JPQLPredicateGenerator.

public class Foo {
   private String name;
   private Set<String> stuff;

  @JPQLFilterFragment(operator = Operator.IN_INSENSITIVE, generator = StringListInFilter.class)
  public Set<String> getStuff(){ return stuff; }
}

public class StringListInFilter implements JPQLPredicateGenerator {
  public String generate(FilterPredicate filterPredicate, Function<Path, String> aliasGenerator) {
     // Does some database specific casting
  }
}

public class FooFilter extends FilterExpressionCheck<Foo> {
   public FilterExpression getFilterExpression(Type<?> type, RequestScope requestScope) {
      Set<String> desiredStuff = getDesired();
      InfixInsensitivePredicate stuffCondition =
              new InfixInsensitivePredicate(
                  new Path.PathElement(
                      Foo.class, String.class, "stuff"), desiredStuff));

   // Doesn't use JPQL logic so isn't the desired where clause

     return stuffCondition;
   }
}
