@VdustR Is there any way that you think of about not turning this into a breaking change, but keep the object support for autocomplete?

While v-model bound with searchTerm, it's already a breaking change in my opinion because searchTerm don't support objects.

Ran into the same problem, and had a look at this Pull Request. I wonder if it could be better to fix this such that searchTerm would be a computed attribute such that if a function like getPlainText is given that function is used to return a String, and otherwise the value as such (or perhaps cast as a String) is returned. Just a thought.... haven't tried that myself yet.

Played around a bit with that idea and came up with a slightly different solution, using just a field name on the item that should return a String. Probably also a breaking change, as parent components that want to update with an Object when an Object is selected will have to listen to md-selected. I'm pretty new to Vue and vue-material, so I've no idea if the following path (against the dev branch version) is any better...
