no innerHTML for anonymous elements?

[StefanoC]

sorry to keep on filling up this group, but i've been searching for
these questions all over!

it looks like innerHTML does not exist (undefined) for anonymous
elements;

snippet:

<binding id="container">
<content>
<xul:div style="" class="container-wrapper">
<children/>
</xul:div>
</content>
<implementation>
<field name="containerEl"
readonly="true">document.getAnonymousElementByAttribute(this, 'class',
'container-wrapper' );</field>
<constructor>
<![CDATA[
console.log(this.containerEl); // works
console.log(this.containerEl.innerHTML); //undefined
]]>
</constructor>
</implementation>
</binding>

the workaround to add something from the constructor (or an handler)
is of course to do an addChild, which works perfectly. still I'm
wondering whether this is a bug or a feature, since I've seen an
example here:
http://www.builderau.com.au/program/web/soa/Creating-reusable-Web-components-for-Mozilla/0,339024632,339186903,00.htm
which does exactly that.

thanks!

console.log(this.containerEl.childNodes); is empty for

> <content>

> <children/>
> </xul:div>
> </content>

but will contain the node <div>Stefano</div> from the following
snippet

> <content>
> <xul:div style="" class="container-wrapper">

> <div>Stefano</div>
> <children/>
> </xul:div>
> </content>

A xul:div is not an html element, so there is no innerHTML property for that.
You'll have to use html:div.

This is correct behaviour. The nodes in this.childNodes aren't listed as
anything else's childNodes, even though that's where they appear to be.

thanks Neil and Martijn !

indeed, html:div works to get an innerHTML even though i still see
some weird behaviors, but I guess I'm one the right track now.

Thanks!
