support for empty-element tags? about delite

AFAIK it works, although I haven't tried it.

Although I'm not sure it is related to the parser, it doesn't work when there are multiple instances declared with a self-closing tag or an instance declared with a self-closing tag followed by an instance declared with a closing-tag:

1. Multiple self-closing tag instances:

<d-self-closing-tag id="instance1"/>
<d-self-closing-tag id="instance2"/>

1. Self-closing tag followed by closing-tag instance:

<d-self-closing-tag id="instance1"/>
<d-self-closing-tag id="instance2"></d-self-closing-tag>

Assuming that buidRendering creates a div child element, in both case the generated DOM structure is:

<d-self-closing-tag id="instance1">
    <d-self-closing-tag id="instance2">
        <div></div>
    </d-self-closing-tag>
    <div></div>
</d-self-closing-tag>

instead of:

<d-self-closing-tag id="instance1">
  <div></div>
</d-self-closing-tag>
<d-self-closing-tag id="instance2">
  <div></div>
</d-self-closing-tag>

I pushed a simple test case in branch https://github.com/seb-pereira/dui/tree/SelfClosingTag

OK, and which browser is it failing on for you?

[seb-pereira]

Tested on desktop browsers FF 26 and Chrome 31.

OK... I'll look but probably it's just a browser limitation that we can't do anything about. You can try checking what the DOM looks like before the parser is called, and see if it's accurate or corrupt.

[wkeese]

I tested this and it's a problem with the browser(s). The browsers interpret markup like:

<d-self-closing-tag id="instance1"/>
<d-self-closing-tag id="instance2"></d-self-closing-tag>

as a DOM structure of:

<d-self-closing-tag id="instance1">
    <d-self-closing-tag id="instance2">
    </d-self-closing-tag>
</d-self-closing-tag>

This happens even when you don't run the parser, even when dui/delite is not even included on the page.

Therefore, AFAICT we just can't support empty elements. Too bad.
