auto-validate issue for paper-input

[bhargavkonkathi]

Hello Team,

When I set auto-validate with required property for paper-input element, and given all spaces without any text characters to paper-input element. After navigating to other element it paper-input doesn't show any error, color or error message or invalidate.

Actual:

Not showing any error or error message when we give paper-input filed with all spaces as input value, by setting auto-validate and required filed.

Expected :

Should show error message and invalidate particular input value and show red color with given message, when paper-input is required filed with auto-validate property.

But if we look at in following URL https://material.angularjs.org/latest/demo/input in this section where demo with Errors section box if we go Client Name it is showing error when we given all spaces. It would be nice if we have same feature in polymer as well.

Even in form validate method also ignoring this edge case. But if we check paper-input with
type ="email" it is showing error like expected only,when user gives all empty spaces.

Thanks.

I'm also finding this issue. When auto-validate="true" and we bind the value of paper-textarea to something (i.e. value="{{inputValue}}"), we get the error: Cannot read property 'textarea' of undefined. We even tried setting the default value of inputValue to empty string or a space, but we still received that error.

Is this in Polymer 1 or Polymer 2? Please provide a JSBin with repro steps, since I can't repro what you mean: http://jsbin.com/xukuxuz/edit?html,output

Hey thanks for the quick response. This is for Polymer 2. This is the JSbin we made. There are errors in the console. It seems like it's mandatory that the initial value of value is empty.

@goatandsheep oh yeah that totally looks like a bug!

@notwaldorf there is a PR resolving this for paper-textarea Polymer 2.0:
PolymerElements/iron-autogrow-textarea#130

I don’t work on Polymer anymore, ccing @e111077 as an owner

Hi, that looks like a bug. We are currently going over a large internal migration that may result in a new major release of paper-input. I'll try to see the fix to this makes it in hat change. The owner of this element is also changing soon, so unfortunately it may be a bit until this gets propagated down the line.
