The Expressions View can handle most expressions which are valid in ColdFusion MX. A good rule of thumb is: if you can write it as an IF condition, on the right side of a CFSET assignment, or within “#” characters, it’s a valid expression.

Expressions are evaluated and re-evaluated only in the context of a suspended request. If no request is suspended, expressions are not evaluated. If a thread is suspended, try clicking on it. This will implicitly tell the Expressions View to re-evaluate its expressions for that request.
