Yes I tried the workarounds for this and was mostly able to get them to work after a lot of tweaking. The one exception was a Combo Box enclosed inside a custom directive.
It used the same configuration and data source as my non-enclosed Combo Boxes, but it blew up complaining about "undefined value of form" or something to that effect. I spent quite a lot of time trying to get that to work before deciding that 1.4.8 worked well enough for me. If you are unaware of this issue I can try to create a reproduction.
