I set up a simple page with a button on it and I get the following error:
Uncaught TypeError: Class extends value undefined is not a constructor or null
The error is in smart.core.js line 405
Here is the code:
<!doctype html>
<html>
<head>
<meta charset=”utf-8″>
<title>Smart Test</title>
<meta http-equiv=”X-UA-Compatible” content=”IE=edge” />
<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″ />
<meta name=”viewport” content=”width=device-width, initial-scale=1.0, maximum-scale=1.0″ />
<link rel=”stylesheet” type=”text/css” href=”source/styles/smart.default.css” />
<script type=”text/javascript” src=”source/smart.core.js”></script>
</head>
<body>
<smart-button>click</smart-button>
</body>
</html>
.
