I am trying to construct a predicate that will succeed if any of the elements of a List, referenced by a Path<List<X>>, satisfy equality for one of the members of X.

However, I cannot determine whether the data can be directly accessed. None of the methods I saw allow access to that data, and I cannot use the existing expression methods to do the above.

Here is code of what I'd like to be able to do, to do this comparison based on the y attribute of the X class:

List<X> xPredicates = new ArrayList<X>();
for(X x : this.getX()) {
    for(X x2: m.get("xList").getActualList()) {
        xPredicates.add(cb.like(x2.y, x.y));
    }
}

Predicate actualPredicate = cb.or(xPredicates);
