[bug]VM2.018a: Switch product to other vendor broken

[nordmograph]

Hello

This was working fine at least on VM2.0.12f so I guess it would be easy to fix:

Now on VM2.0.18a
On  the product edition page, switching to another vendor using the dedicated select list field and saving , doesn't save the new selected vendor and only reloads the previous one.

It seems when saving the page that the older value comes back before the form is submitted.
So it could be a javascript problem.
Chrome mentions:
Uncaught TypeError: Object [object Object] has no method 'dynoTable'

Hope it helps and we can fix this quick.
