[Product-Developers] Problem with ordering of objects from a new product

[cristopher pierson ewing]

Gilles,

Thanks for the suggestion.  As it turned out, I found that the problem was 
in the moveObjectByDelta method of the OrderedFolder class.  The problem 
in our case was that our content types, although perfectly functional, 
were not listed as CMF objects, so the method above failed silently by 
passing over any request to move those objects.  We fixed the FTI for the 
classes in our product, and all is working now.
