Unless I do a full page reload I get this on my input fields:

I'm using Turbolinks which swaps out parts of the page instead of doing a browser refresh. Because of this javascript that is triggered when the file is loaded (rather than binding to page events) does not get triggered. I would imagine the same bug will occur with $.load() but have not tested this.

Selecting the input field fixes this. It seems like this behavior is defined in "forms-free.js". The user-interaction events are triggered from "$(document).on()", which works fine even after swapping out part of the document body. However some code is triggered inline and will not be executed again.

Here is the html:

<form method="post" id="BriefingTaskForm" data-js-ajax-form="" action="/BriefingTask/Submit">
    <input data-val="true" data-val-required="The ProcessInstanceId field is required." id="ProcessInstanceId" name="ProcessInstanceId" type="hidden" value="acd75b47-880b-4378-8c36-0c971c0449d0">
