I know this is a long shot... The change to Core has been a bit daunting. I've worked through everything (my prior plugins, scheduled tasks, etc.) - save for this last problem. A while back I bought the source code to a Stripe plugin thinking that would 'future proof' me. I've made changes (e.g., a ViewComponent, etc.) but I now get:
"The model item passed into the ViewDataDictionary is of type 'Nop.Web.Models.Checkout.CheckoutPaymentInfoModel', but this ViewDataDictionary instance requires a model item of type 'Nop.Plugin.Payments.Stripe.Models.PaymentInfoModel'."
As I mentioned, I know this is a long shot, but is this error 'instantly recognizable' to any one? I've worked more 'around' Nop than 'inside' it, so any pointers would be much appreciated.
