Re: [eclipselink-users] Data updated during aboutToInsert isnt getting p

[James Sutherland <jamesssss@xxxxxxxxx>]

At the point of the aboutToInsert event the row to insert has already been
built.  To effect the insert, you need to modify the row
(event.getRecord()).  The preInsert event is raised before the row is built,
so you could change the object in preInsert.
