$setViewValue revalidate parameter

[dimirc]

I see that $setViewValue has a third parameter (revalidate) that I'm setting to true to force $parsers to run and recreate $modelValue

this.$setViewValue = function(value, trigger, revalidate) {
https://github.com/angular/angular.js/blob/master/src/ng/directive/input.js#L1928

At the docs I don't see this third parameter documented, is it save to use it?

I'm using it on this PR angular-ui/ui-select#138

This (the revalidate parameter) is a private API which is going to be removed soon, most likely. It was added as a hack to make sure that the native validators would be re-run even if the value technically didn't change. This is going to be done better in the near future...

You should not use it in angular-ui. @matsko's form refactoring will likely make it useless and we will be able to revert it.

/cc @matsko please inform me if you've already made that "feature" redundant, because it would be really nice to get rid of it

@caitp how will you suggest to force this rerun then?

In the future, most of this stuff will be moved out of $parsers/$formatters, and you should be able to just use the validate() api which is already exposed. Currently validate() isn't enough for this because the code which we need to revalidate lives in parsers/formatters, but it won't soon (I hope!)
