Non-assignable model expression, It seems that Issue #1435 is back in 1.0.7...

[rgraffconnect]

When using = in an isolate scope like: { selected: "=" } and not setting the assigned attribute on the element, the following error appears:

Non-assignable model expression: undefined (directive: ...)

I'm seeing this issue in 1.0.7 and getting an error when using =?

Error:
Invalid isolate scope definition for directive ...: =?

Is this issue back!??

As I wrote in #1435, the feature is not available in the 1.0.x branch. Please close the issue, thanks!
