tapestry5.3 and Twitter-bootstrap disabled inputs

[Jaypax Ginete]

I have been able to use twitter-bootstrap for my layout. But I have 
encountered a problem when I'm trying to use "single" attributes. Doing 
something like:

<input type="text" placeholder="${name}" disabled/>
The "disabled" attribute causes a "Failure parsing template: Attribute 
name "disabled" associated with an element type.." exception.

Is there a workaround for this?
