> This can be replicated by clicking Feature Demos >> Skin Demo from the trinidad-demo
of trinidad 1.2.x.
> The error occurs when it tries to resolve variables like #{prefs.proxy.skinFamily}. 
When inside the skins demo page, prefs.proxy returns #{sessionScope}.  In the trinidad-demo
from trinidad 1.0.x, #{sessionScope} resolves to the session map.  But in trinidad 1.2.x,
#{sessionScope} does not resolve to the session map but instead returns the string literal
"#{sessionScope}".  The problem is when EL tries to look for the property skinFamily from
the string literal "#{sessionScope}".  This is when it throws the javax.el.PropertyNotFoundException.
> A quick workaround would be to replace #{prefs.proxy.skinFamily} with #{skinFamily} in
trinidad-config.xml.  Same with the other properties.
> I'm still looking into this and will update this entry when I find a good fix.
