JPQLQuery loses nulls last/first for nested properties #1503

I'm trying to generate a JPQLQuery which is order by a field in nested property. So I do something like this:


And the relevant part in the resulting sql looks like this:

order by devic1_.connection_time desc  

So the nulls last is missing.

Looking at my debugger, I can see that the place where the null handling value is reset is the -class.

public final T orderBy(OrderSpecifier<?> spec) {
        Expression<?> e = convert(spec.getTarget(), true);
        if (!spec.getTarget().equals(e)) {
            metadata.addOrderBy(new OrderSpecifier(spec.getOrder(), e));
        } else {
        return self;

It seems that after the conversion, the first branch gets chosen and there is a call to the two argument OrderSpecifier -constructor that looks like this:

public OrderSpecifier(Order order, Expression<T> target) {
        this(order, target, NullHandling.Default);        

So much for my nulls last then.. Shouldn't the orderBy -method in the QueryMixin -class also copy the null handling value over to the new OrderSpecifier?
