Hi, I have found an issue in ordering by a method. I have two entities : Invoice and InvoiceItem ... this query: (I know, it's not very efficient...) select i from Invoice i order by i.getPrice() desc/asc it gives the same order for desc and asc (every time asc) When the float is not calculated (only returned

== 0)) ORDER BY r.startDateTime DESC If we remove the ORDER BY part, the query completes OK and returns the records from the DB, but obviously not in order . Here is the stack trace of the exception ... $200(EventQueue.java:103)         at java.awt.EventQueue$ 3 .run

performance I noticed a strange behaviour where an ORDER BY - directive isn't executed as it should be (and usually is, except in this special combination-case). Ordering seems to be ignored if we order by a simple member (e.g. a String) being the Entity-ID and, at the same time, filter

Hi! Is there a way to NOT prefer NULL in Order BY? I.e. assume this: @Entity class Hint {   ... do something like SELECT FROM Test ORDER BY hint.name It orders ASC like this (assuming I've got ... } and third one to NULL: Test 3 (with hint = NULL) Test 1 (with hint = A ) Test 2 (with hint = B) And descending: Test 2
