    <p>I am in the process of integrating extJS with Grails.</p> <p>Below is my list action in my music.TuneController. </p> <pre><code>def list = { def tuneInstanceList = new ArrayList&lt;Tune&gt;() def tune= new Tune(); tune.playerId = "ASDF"; tune.playerPrice= "100"; tuneInstanceList.add(tune); def listResult = [ total: tuneInstanceList.size(), items: tuneInstanceList] render listResult as JSON } </code></pre> <p>My code in tune-grid.js</p> <pre><code>/* * Ext JS Library 2.0 Beta 1 * Copyright(c) 2006-2007, Ext JS, LLC. * licensing@extjs.com * * http://extjs.com/license */ Ext.onReady(function(){ // create the Data Store var ds = new Ext.data.Store({ autoLoad: true, proxy: new Ext.data.HttpProxy({ url: 'http://localhost:8080/music'}), reader: new Ext.data.JsonReader({ results: 'total', root:'items', id:'id' }, [ {name: 'playerId' }, {name: 'playerPrice'} ] ) }); var cm = new Ext.grid.ColumnModel([ {header: "Player Id", width: 120, dataIndex: playerId }, {header: "Player Price", width: 180, dataIndex: 'playerPrice'} ]); cm.defaultSortable = true; // create the grid var grid = new Ext.grid.GridPanel({ ds: ds, cm: cm, renderTo:'grid-example', width:540, height:200 }); }); </code></pre> <p>list.gsp:</p> <pre><code>&lt;%@ page import="music.Tune"%&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /&gt; &lt;meta name="layout" content="test" /&gt; &lt;g:set var="entityName" value="${message(code: 'song.label', default: 'Song')}" /&gt; &lt;title&gt;&lt;g:message code="default.list.label" args="[entityName]" /&gt;&lt;/title&gt; &lt;g:javascript library="tune-grid"/&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="body"&gt; &lt;!--&lt;g:javascript library="examples"/&gt;--&gt; &lt;!-- EXAMPLES --&gt; &lt;div id="grid-example"&gt;&lt;/div&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>When the action is called , I get the below as the output. It seems that the control doesnt get to the list.gsp at all.</p> <pre><code>{"total":1,"items":[{"class":"music.Tune","playerId":"ASDF", playerPrice":"100","playerDep":null}]} </code></pre> <p>Could you tell me what I am doing wrong here?</p> <p>Thanks!</p>

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).
