Functions with expressions about springfilter HOT 3 CLOSED

That's an interesting use case. You can't do that with the size function as JPA expects a collection expression and you are providing a predicate (bool) expression. There is actually a subquery going on here, not sure how to handle it. The CriteriaBuilder's count method may be used somehow, I will try to think about it. Feel free to contribute (the class handling functions is not very well written, sorry for that).

I just read the issue again, and the statement find every car with at least 4 wheels with a diameter >=10 should be equivalent to /car?filter=size(wheels) >: 4 wheels.diameter >: 10.

Not sure it completely solves the issue though.

I have added support for the exists function. It may possibly answer this issue.

Closing for now.
