I don't know if this is relevant to the problem, but you don't need to
use 'setAttribute' for built-in attributes of HTML element:
this.content.id = this._name + "_content";
avoids an unnecessary function call.
For the DOM attribute 'class', the Javascript binding requires you to
use 'className', because 'class' is a reserved word in Javascript:
this.content.class = "fullContent";
(or, using a Prototype method)
this.content.addClassName('fullContent');
This is not quite the same, because if you already have a class on the
element, this will add the new class, whereas the simple assignment
will replace it. But since you have just created the element, there is
no difference.

IE objects (correctly) to your using the Javascript reserved word
'class' as an object key: Firefox is more lax and lets it through.
'id' will work without quotes.

I don't know. Your example seems to match that in the Prototype
documentation. I would try it with 'className' instead of 'class' and
see whether this works.
