Pagination::totalCount initialized incorrectly

[taobig]

What steps will reproduce the problem?

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
            'totalCount' => $totalCount,//the value is difference from $query->count()
            'pagination' => [
            ],
        ]);
        echo $dataProvider->pagination->page;//always 0

What is the expected result?

$dataProvider->pagination->page == $_GET['page']

What do you get instead?

$dataProvider->pagination->page;//always 0

Additional info

correct code：

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
            'totalCount' => $totalCount,//the value is difference from $query->count()
            'pagination' => [
                totalCount' => $totalCount,// add this line
            ],
        ]);

or

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
            'totalCount' => $totalCount,//the value is difference from $query->count()
            'pagination' => [
            ],
        ]);
        $dataProvider->getModels();// add this line

I found yii\data\Pagination::getPageCount() to use totalCount without initialized.

Yes. That's how it is currently. Any idea on how to fix it?

@GHopperMSK would you please check regression that's caused by solving this task? yiisoft/yii2-elasticsearch#201 Thanks!

Fixed in in ElasticSearch. Probably a good idea to release it first.
