Thankyou very much for this post. I am Using a CB/VM File uploaded and I found it wan;t populating the jos_product_mf_xref table with a manufaturer.

Made a few simple code changes, Ran through the db and added the rows needed and it worked perfectly!

Thought I had a major problem on my hands when re-installing didn;t seem to resolve the issue.
