      The <classname>cascade-save</classname> operation was incorrectly handling auto-incremented Primary Key (PK) tables that linked to parent tables with an assigned PK. The fix now allows the <classname>cascade-save</classname> operation to handle the parent-child relationship between tables.

    Description

      Consider:

      a table with an assigned PK (i.e. not auto-increment), let's call this "A"
      Another table ("B") linked to the table listed above but with it's PK set to auto-increment.
      Now if you try to save B with cascading switched on, it will break. From the little debugging I've done it looks like:

      a) hibernate detects that A needs to be saved first, but puts it into some sort of queue.
      b) when it hits B, it short-circuits this save queue and tries to save B immediately so as to obtain a PK reference for B. This fails since A hasn't been yet been saved so it's link is still null.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
