Curly braces dont work for data binding within ActionScript in the
manner you suggest:
* Expecting colon before dot.
* Syntax Error: rightbrace is unexpected.
* Expecting rightbrace before semicolon.
Those are the compile errors encountered. Perhaps there is another wya
to use dataBinding from ActionScript? Or alternatively, there may be a
way to completely define this component in MXML, allowsin us to use the
curly-brace notation for databinding?
