Date discreapncies between Formatter::asDate() and FormatConverter::convertDateIcuToJui() discrepancies

[tom--]

I noticed the following differences when using jQuery-UI Datepicker. Formatter was providing the date input's initial value on page load and the format changed after using Datepicker.

Both are ICU 'medium'.

locale	asDate()	convertDateIcuToJui()
en-US	Apr 4, 2015	Apr 4 2015
ru-RU	04 авг. 2015 г.	04 Авг 2015 г.

or something like that

I am unable to reproduce this, do you have the PHP intl extension installed?

The discrepancy has changed since I last tested it.

intl 1.1.0
ICU 52.1
PHP 7.0.11

In app config

    'language' => 'ru-RU',

Model and controller

<?php

class TestForm extends \yii\base\Model
{
    public $date = '2016-11-27';
}

class TestController extends \yii\web\Controller
{
    public function actionTest()
    {
        return $this->render('test', ['model' => new TestForm()]);
    }
}

View

<?php $form = \yii\widgets\ActiveForm::begin(); ?>
<?= $form->field($model, 'date')->widget(\yii\jui\DatePicker::className(), ['dateFormat' => 'medium']) ?>
<?php \yii\widgets\ActiveForm::end(); ?>

Initial page load

Click on 27 Nov in the date picker

Date is now formatted as

i cannot be sure that intl was installed when i ran the test in aug last year but it most likely was because i have required it as standard for years

@bscheshirwork thanks for the detailed research. I just looked into the jquery UI sources and found that they have hardcoded the month names:

@cebe
So... This issue can be moved to yiisoft/yii2-jui and can be remove from milestone 2.0.13?
