It's been a few days (almost a week). I was able to get the basics on the form items to load in back on the 15th, however didn't make much progress since then. I was able to get back to development today and was able to properly implement a products ability to select the Currency Locale (and retain it between runs) as well as vendor selection. If a product doesn't have a vendor assigned, it will use the "[No Vendor]" item - which greys out all vendor specific information. The dropdown allows for users to easily switch the vendor to whatever ones are defined. I've placed a screenshot below showing the currency properly loading and the Purchase Price field using the associated currency format, as well as how the Vendor Information section behaves when the [No Vendor] item is selected.
I'm likely not going to get much development in for the rest of the week as I'll be packing tomorrow night for my work trip, and spending Tuesday through Thursday on said work trip.
There's obviously a lot more work to do, but I want to focus on implementing the following so we can work towards an Alpha status, allowing feedback on the current changes while allowing us to work on the features that are missing.
Guess that's all for now - please let me know your thoughts and if you'd like to participate in the Alpha!
