This bug is supposed to be fixed in Alfresco 3.3, but, according to the information contained in the bug, it has already been fixed in CHK-8588.
My problem is that I have to release the application quite soon and I cannot afford to wait till Alfresco 3.3 is released. Therefore, my question is: Is there any mean to install a concrete bug fix without having to upgrade the whole Alfresco version?
