The list will be sorted only by the last field attached are junit path file to show the bug, and a fix (there is also a junit that shows the fix is wrong) watch out that in the Junit test patch the test is called "testFailMultipleOrderings" and it will path only because i am using there "assertNotSame" the fix is : The OrderExitOperation class should hod a list of properties to sort by and then the comparator should iterate over all the properties by their insert order the comparator algorithm: if the object are identical return 0; else compare the properties if the properties comparison returns 0 go to next property else return the comparison (the comparison should be multiplied by -1 in cases of descending order.) I am also attaching a test to show this error, and its fix -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
