    <p>try using just one store. It has to have a 'virtual' root node containing as many items as root nodes you want in the first level and set rootVisible: false in the tree. In this way you will have a tree like below:</p> <pre><code>non-visible root | +-- first root | : | +-- second root : </code></pre> <p>But given that you set rootVisible: false, what you will see is</p> <pre><code>+-- first root | : | +-- second root : </code></pre> <p>UPDATE This is the json that i have in my project (i have a tree that shows more than just one root)</p> <pre><code>{ "actions" : [{ "action" : "Version 1.3.21.0", "url" : "/Operations/Version%201.3.21.0" }, { "action" : "Version 1.3.16.0", "url" : "/Operations/Version%201.3.16.0" }] } </code></pre> <p>and this is the model that i use:</p> <pre><code>Ext.define('App.model.PluginAction', { extend : 'Ext.data.Model', fields : [ {name: 'text', mapping: 'action'}, 'url', 'description', { name: 'leaf', convert: function(val, data) { return data.raw &amp;&amp; data.raw.children; }} ], hasMany : { model: 'PluginAction', name: 'children'}, idProperty: 'text' }); </code></pre> <p>And my tree class definition:</p> <pre><code>Ext.define('App.view.layout.PluginActionTree', { extend: 'Ext.tree.TreePanel', alias: 'widget.pluginActionTree', hideHeaders: true, rootVisible: false, useArrows: true, lines: false, containerScroll: true, autoSize: true, layout: 'fit', model : 'App.model.PluginAction' } </code></pre> <p>Good luck!</p> <p><strong>Update:</strong> The problem is that trees can only have just one and only one root node. Once you know it what you have to do is create a root node (which will be hidden) and that root node has to have as many nodes has you need.</p> <pre><code>Ext.create('Ext.tree.Panel', { xtype : 'treepanel', hideHeaders: true, rootVisible: false, // this is important containerScroll: true, autoSize: true, layout: 'fit', root: { children : [ { text: 'root1' }, { text: 'root2' }] }, renderTo: Ext.getBody() });​ </code></pre> <p>this works! please, take a look at <a href="http://jsfiddle.net/FDY6v/" rel="nofollow">http://jsfiddle.net/FDY6v/</a> </p>

    3. COi´ve updated the answer. your json looks right but remember that trees make a new call for load data everytime you expand a node in order to get the rows to create the subtree.

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).
