Subject Re: PK Generator Status
Date Fri, 08 Jul 2005 12:25:07 GMT
Gianny,
	My understanding of AutoIncrementPrimaryKeyWrapper is that it
executes an insert on some table during the PK generation phase.  I
thought that couldn't be the "entity table" since then when the entity
goes to insert itself it would find that the row already existed.  How is
it that the AutiIncrement PK generator communicates to the entity that its
row already exists?

Thanks,
	Aaron
