--------------------------------------------------

Hi Jason - thanks for the quick response.  We started our migration last year before this announcement and are a far way in.  We also wanted to start using CDI, JSF 2, and RichFaces 4 items without building more seam 2.3 items to just have to migrate at some future point.  We have many things working on Seam3, this issue though we are having issues with.  Does DeltaSpike solve this?  DeltaSpike seems to be in beta, 0.4-incubating-SNAPSHOT, I do not think we can move there right now.

I did not follow this thread, for the read operation only (no many to many editing), what was the solution?
