Is it possible to indirectly bind a component reference in the Expression language?

E.g.  
`{Root Container.%.text}`  
where `%` is a variable, e.g. `% = 'lblValue'`

Nope. Out of the box, only runScript with a component’s custom method’s `self` can give you dynamic access to the window environment. Simulation Aids offers a somewhat more flexible approach.
