Hi Phil,

the expression fails because you do not pass in the current  
WorldMorph. When you do that (http://livelykernel.sunlabs.com/repository/lively-wiki/testworld.xhtml 
) then everything works fine.

Like I mentioned before you can use this.setOpacity(0.3); instead of  
this.rawNode.style.setProperty('opacity', '0.3');
