ng-maxlength/ng-minlength validation not working for input type text

[infowebster]

We just updated the angular libraries from 1.3.0-beta.5 to 1.3.0-beta.15 and noticed that the input fields with input type number and min- or maxlength validation set are always invalid.

When you use the Plunker of the api reference (https://code.angularjs.org/1.3.0-beta.15/docs/api/ng/input/input%5Bnumber%5D) and add the attributes ng-minlength or ng-maxlenght it can be reproduced that starting with beta.12 the input field will be always invalid.

I looks like that 'value.length' in the min/maxlength directive is invalid as the int value has no length.

I've also noticed issues relating to validation in the beta.15.

For example ...

input marked with "ng-required" does not work - but strangely "required" does.
