huh, so based on my read the POST will end up in `args[0]` and get passed along to the form. however it looks like the logic below was designed to allow the POST to override what was already in the `plan_version` if it existed, which seems like it is now no longer able to do (unless that somehow implicitly happens in the form superclass). again, sorry if comments aren't helpful, not 100% clear on what's going on here just happened to lurk.
