Re: [eclipselink-users] duplicate assignments to same column in update
|
Very odd,
When the error occurs, does it always occur for that same deployment, or
does it sometimes fail, sometimes pass with the same run?
I assume it is related to association overrides and the multiple Embedded
Money relationships. If you comment out these in tern, does the issue go
away?
