So that we can have non string values, e.g. ng-value="true" for radio inputs
Breaks boolean attrs are evaluated rather than interpolated
To migrate your code, change: <input ng-disabled="{{someBooleanVariable}}">
to: <input ng-disabled="someBooleanVariabla">
Affected directives:
* ng-multiple
* ng-selected
* ng-checked
* ng-disabled
* ng-readonly
* ng-required

@name Cookbook: Advanced Form

@description
|
|
|
|
Here we extend the basic form example to include common features such as reverting, dirty state
|
|
detection, and preventing invalid form submission.

#Things to notice
|
|
|
|
* Cancel & save buttons are only enabled if the form is dirty — there is something to cancel or
|
|
save.
|
|
* Save button is only enabled if there are no validation errors on the form.
|
|
* Cancel reverts the form changes back to original state.
|
|
* Save updates the internal model of the form.
|
|
* Debug view shows the two models. One presented to the user form and the other being the pristine
|
|
copy master.
