    <p>I'm trying to return some JSON from my Spring webapp using Jackson and parse it and load it into a jqGrid.</p> <p>I've got the data coming back and visible in Chrome via the JSONViewer extension. It looks correct to me.</p> <p>Local tests with arraydata have been successful.</p> <p>Here's my JSP/HTML/JS:</p> <pre><code> &lt;link rel='stylesheet' type='text/css' href='http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/themes/ui-darkness/jquery-ui.css' /&gt; &lt;link rel='stylesheet' type='text/css' href='css/jqGrid/ui.jqgrid.css' /&gt; &lt;script type='text/javascript' src='js/jquery-1.7.1.min.js'&gt;&lt;/script&gt; &lt;script type='text/javascript' src='js/jquery-ui-1.8.17.custom.min.js'&gt;&lt;/script&gt; &lt;script type='text/javascript' src='js/i18n/grid.locale-en.js'&gt;&lt;/script&gt; &lt;script type='text/javascript' src='js/jquery.jqGrid.min.js'&gt;&lt;/script&gt; &lt;script type='text/javascript'&gt; $(document).ready(function () { jQuery("#list").jqGrid({ url:"formSubmit.html", datatype: "json", height: 700, width: 1100, colNames: ['ReqID', 'Family', 'ControlID', 'Name', 'Description', 'Category','Priority', 'Notes', 'Parent'], colModel: [ { name: 'reqID', index: 'reqID', width: 40 }, { name: 'family', index: 'family', width: 100 }, { name: 'controlID', index: 'controlID', width: 100 }, { name: 'reqName', index: 'reqName', width: 175 }, { name: 'requirement', index: 'requirement', width: 450,cellattr: function (rowId, tv, rawObject, cm, rdata) { return 'style="white-space: normal;"' } }, { name: 'category', index: 'category', width: 100 }, { name: 'priority', index: 'priority', width: 100 }, { name: 'requirementNotes', index: 'requirementNotes', width: 100 }, { name: 'parent', index: 'parent', width: 100 } ], rowNum: 10, rowList: [10, 20, 30], pager: '#pager', viewrecords: true, jsonReader : { repeatitems: false } }); jQuery("#list").jqGrid('navGrid', '#pager', { edit: false, add: false, del: false }); }); &lt;/script&gt; &lt;table id = 'list'&gt;&lt;/table&gt; </code></pre> <p>Here's some data coming back from my Spring container using Jackson:</p> <pre><code>{ "total":"1", "page":"1", "records":"558", "rows":[{ "parent":"", "priority":"", "requirementNotes":"DummyData", "category":"DummyData", "family":"DummyData", "requirement":"DummyData", "reqID":"1", "controlID":"DummyData", "reqName":"DummyData"}] } </code></pre> <p>I'm consistently getting back an Uncaught TypeError cannot read property '0' in undefined as my response in jquery.jqGrid.min.js:23 and I'm stumped.</p>

    1. COit's very strange that the `url` option which you use in jqGrid has `.html` extension and contains (or generates) JSON data (response). Should the `url` be not URL to your MVC Controller? Another strange, but not critical thing is that you use CSS from jQuery UI 1.8.6, but JS from jQuery UI 1.8.17.

    2. COMy Spring MVC controller's @RequestMapping points to a "virtual" html file. I didn't expect this to be a problem...but at this point I'm anxious to eliminate variables...

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).
