Upgrading from ver 1.8.5 to 1.8.8 gives the following error message when reloading page.
I stripped the code down and it seems to be the using() function causing the problem:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1" />
<script src="jquery/jquery-3.4.1.min.js"></script>
<script src="easyui/easyloader.js"></script>
</head>
<body>
<link href="my.css" rel="stylesheet" />
<div id="dlg"></div>
<script type="text/javascript">
using(['tabs', 'layout'], function () {
});
</script>
</body>
</html>
Any ideas?
