    <p>I have a dataview list that fetches data from the server, puts it in a store, and renders into a template. Standard stuff.</p> <p>Above the dataview list in the UI is a button bar containing some Ext.Buttons. I want to be able tap a button and filter the list based on the name of the button. For example: click on 'English 9A' button and show items in the list with the '<strong>title</strong>' of 'English 9A'.</p> <p>As of now when I click the button, the list disappears and I get a console error of: "Uncaught TypeError: Cannot read property 'position' of undefined " and a loading spinner where the list was.</p> <p>I know there are similar questions out there but I've tried all the solutions but no luck at all.</p> <p>Sample json data:</p> <pre><code>{ "ftype":"Announcement", "value":{ "created":"7/18/2013 05:40:06 PM", "content":"Hello class, it is July 29th.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
