Description (last modified by bill)


Click on:


A web page that displays a normal html button and a tundra button


Both buttons should be tundra styled


The first button is constructed by a widget which have the following templateString:"<button dojoType="dijit.form.Button">Button 1</button>". The dojoType fragment is ignored because it is at the root of the hierarchy.

The bug is here reproduced with a button as the root of the template, which is an uncommon occurence, but it also prevents having Layout or ContentPane? as the top level of the template, which is IMO much more serious.

At minimum the "widgetsInTemplate:true" code should raise an error if the top-level element have a dojoType attribute.

Forgot this ticket was here; I wrote about this issue in

As I said in the linked comment, the problem is that in the generated DOM, the main widget's id and the templated widget's id will try to be applied to the same node. I can't think of a solution currently, although I do sympathize w/the problem you are saying about not being able to have a layout widget as the root of your template.

The way to get this to work (with the current code) is to mix in the classes you want into _TemplatedMixin. I.E. instead of trying:

declare("MyWidget", [_WidgetBase, _TemplatedMixin], {
   templatedString: "<div dojoType=dijit/Menu>...",

Do this:

declare("MyWidget", [_WidgetBase, _TemplatedMixin, Menu], {
   templatedString: "<div>...",

It's not officially supported, but will probably work.

To support this better in the future, we could conceivably give _Templated a factory method, like _Templated.compile() or _Templated.create(), that would take an optional superclass X (or multiple superclasses), and a template string, and return a new constructor XTemplated. To be used like:

_Templated.create(null, "<div data-dojo-type=dijit/Menu>...")

It could also define XTemplated.UnTemplatedClass (or some better name) to point to X, in case someone needed access to that original class at some point.

That would be a big change, albeit interesting.
