Re: [eclipselink-users] Lifecycle methods (or how do I default columnval

["Tim Hollosy" <hollosyt@xxxxxxxxx>]

I think I may be running into - bug 224416
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=224416)

Is there some setting you have to do in order to get lifecycle stuff
to work? Is it dependent on weaving maybe?

I'm not really sure of a work-around at this time for doing things
like setting default values. So any help would be appreciated.

Thanks,
Tim
