Hi there,

Don't have the problem isolated into a fiddle yet, but just a heads up that a use case for watching objects seems to have broken from 0.11.5 to 0.11.6 (We noticed this when a developer on my team got a new computer and was using the same code as us but the app wasn't working, noticed the difference in Vue versions, downgraded back to 0.11.5 everything was good)

Component Alpha watches its own property 'foo', which is passed in to it via v-with from the parent component Beta.

In the template, <div v-component="alpha" v-with="foo: parentFoo"> (not sure if this matters, but the component alpha is also in a v-repeat)

Beta sets parentFoo in its compiled hook via this.$set('parentFoo', {key1: val1, key2: val2})

In 0.11.6, the child component (alpha)'s foo will be undefined

Fiddle incoming (either lunch of after work)
