TYPO3 Core

To resolve this issue, we must call a jQuery function when clicking on the view button.
The function is basic, she must get the href property of the button and then use window.open.

Someting like :

// Add event to view button
$('.t3-icon-document-view').parent().on('click', function (event) {
    window.open($(this).attr('href'), '_blank');
    event.preventDefault();
    event.stopPropagation();
});

Then we must change the button viewHelper to :

<f:be.buttons.icon uri="{url}" icon="actions-document-view" />

Thanks
