Re: [eclipselink-users] [MOXy] overriding mapped xpaths in inheritance h

["polly.c.chang" <polly.c.chang@xxxxxxxxx>]

Hi Blaise,

Cool, thank you for looking into this.  I was going to test it and post
back, but I have been backed up as well.  The bug report looks good.

So what happens if you unmarshal this kind of mapping?  Does the Child's
mapping for "field1" get used instead of the Parent's?

Thanks!
