There is no way (it seems) to use the <cfdump eval=myObject> within cfscript.
If you try:
myPerson = new Person();
you get a:
invalid call of the function dump (/Applications/Railo/lib/railo-server/context/library/function/dump.cfm), 13th Argument (eval) is of invalid type, can't cast Object type [Component Person] to a value of type [string]
and if you use:
you get a :
Missing [;] or [line feed] after expression
