    <p>I've configured my store as:</p> <pre><code>var store = new Ext.data.JsonStore({ url: 'gridData.php', root: 'movies', fields: ['film_id', 'title', 'release_year', 'rating'] }); </code></pre> <p>and then defined my grid as:</p> <pre><code>var grid = new Ext.grid.GridPanel({ title:'Movies', store: store, columns: [ { header: "ID", width: 30, dataIndex: 'film_id',sortable: true, hidden:true }, { id: 'title-col', header: "Title", width: 180,dataIndex: 'title', sortable: true }, { header: "Rating", width: 75, dataIndex: 'rating',sortable: true }, { header: "Year", width: 75, dataIndex: 'release_year',sortable: true, align: 'center' } ], autoExpandColumn: 'title-col', renderTo: Ext.getBody(), width: 600, height: 300, loadMask: true }); </code></pre> <p>then I load the store:</p> <pre><code>store.load(); </code></pre> <p>I'm doing all this in <code>Ext.onReady</code> method. The data that I want to display is fetched from a php file which is of the following form:</p> <pre><code>{ "count":2, "movies":[{ "film_id":"1", "title":"ACADEMY DINOSAUR", "description":"An Epic Drama of a Feminist And a Mad Scientist who must Battle a Teacher in The Canadian Rockies", "release_year":"2006", "rating":"PG", "special_features":"Deleted Scenes,Behind the Scenes" }, { "film_id":"2", "title":"ACE GOLDFINGER", "description":"An Astounding Epistle of a Database Administrator And an Explorer who must Find a Car in Ancient China", "release_year":"2006", "rating":"G", "special_features":"Trailers,Deleted Scenes" } ] } </code></pre> <p>When the page is loaded, the grid keeps showing the loading mask and the data is never shown. Also, I get the error <code>a is undefined.</code> What am I missing?</p> <p><strong>Edit</strong></p> <p>I've found that there's some path issue when assigning URL to store but still can't resolve. My "gridData.php" file, JS file and the HTML file where the grid is being displayed, are in the same folder and I'm on "localhost/myapp". Please help!</p>

    1. COFyi, I copied your code and ran it on ExtJS 3.3.1, and it runs as expected. No error found. One thing I would suggest is check your PHP code. Make sure the returned JSON is clean and valid. From what I see the JSON seems to be hard coded in some manner. Some spacings doesn't seems natural from `json_encode`.

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.

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