<p>When I Run my widget that closes one window and initializes a controller to display another window, I get error : </p>

<pre><code>Application Error
Runtime Error: unknown Exception

</code></pre>

<p>Can someone please guide on where can I find the file for this error  so I can try-catch this error for better understanding or detail on this....
Also if someone can explain this error.</p>
