    <p>I'm trying to develop a table of content style widget for a map in my web application. The widgets works quite well in Chrome and FireFox but fails silently in internet explorer 8 (I have read that so many times while developping this application!)</p> <p>I'm using the dojo framework and I figured out that it fails between the BuildRendering and PostCreate methods of the widget lifecycle. The widget is created using a graph structure so it is recursive. Does anyone have any idea what can cause failure between these two methods of the widget life cycle?</p> <p>I have read in some places that the template may be a problem, so I've included it following my Node code.</p> <p>Here's a simplified version of the widget so you can maybe get an idea of what's happening :</p> <pre><code>define(['dojo/_base/declare', "dijit/_WidgetBase", "dijit/_TemplatedMixin", "dijit/_WidgetsInTemplateMixin", "dojo/text!./templates/_Node.html"], function (declare, _WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin, template) { var _Node = declare ([_WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin], { templateString : template, _childNodes : [], constructor : function (params, srcNodeRef) { lang.mixin(this, params); this.inherited(arguments); }, buildRendering: function (){ this.inherited(arguments); // Execution leaves this function but never launches postCreate() // buildRendering is not actually there in my code, I just have it here for // debugging this particular problem. }, postCreate : function () { // Execution never reaches this point in IE8 (probably 7 and 9 as well) var newParams = { "Para1": "Value1", "Para2": "Value2" } var newNode = new Node(newParams, this.containerNode); this._childNodes.push(newNode); } }); return _Node; }); </code></pre> <p>And here's the template it uses:</p> <pre><code>&lt;div&gt; &lt;div data-dojo-attach-point="rowNode" data-dojo-attach-event="onclick:_onClick"&gt; &lt;span data-dojo-attach-point="contentNode"&gt; &lt;span data-dojo-attach-point="checkContainerNode"&gt;&lt;/span&gt; &lt;img src="${_blankGif}" alt="" data-dojo-attach-point="iconNode"&gt; &lt;span data-dojo-attach-point="labelNode"&gt;&lt;/span&gt; &lt;/span&gt; &lt;/div&gt; &lt;div data-dojo-attach-point="containerNode" style="display: none;"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p>So my node follows this structure but like I said, silently fails between buildRendering and postCreate in Internet Explorer. I've spent quite a bit of time on this already. I hope someone can give me a hand here.</p> <p>And please don't look at the syntax too much, I copy pasted parts of my code but I modified it heavily for clarity.</p> <p>Thanks,</p> <p>Ggilmann</p>

    1. COI can't say that my answer will solve your problem, but I just listed a few things that I noticed when reviewing your code.

    2. COI've copied your code and ran it in both Firefox and IE8, it seems to work perfectly in both. Have tried running in IE7 mode, quirks mode, compatibility mode, ...etc, all work. I'm guessing what is breaking this is something not included in the modified version above. My bet would be on that something in the template is breaking it as this is being fetched and included during buildRendering. Have tried to break it by not including an _onClick() class method or _blankGif property but these have no specifically destructive in IE8.

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).
