UDcodes list in combo box are empty after upgrading

Upgrading from 10.0.700.2 to 10.2.300.9 (testing phase here not yet live… )

I noticed the User codes lists in added combo boxes are showing empty.

I seem to remember seeing this passing by in this blog but cannot find it… was there a resolution for this or I should open a ticket at Epicor?

Thanks

Pierre
