Only if you specify isDefined("request.form.whatever") -- however --
if you created a structure called "form" in the variables scope (bad
idea anyway) then this might occur. Though on general principal, I
agree with the use of StructKeyExists() if at all feasible when you
know that the target variable is only one below your known-to-exist
structure. I.e. if you know that request.x.y exists and is a
structure, use structKeyExists(request.x.y,"z") -- if on the other
hand you're not certain if request.x.y exists or is a structure or
that request.x exists or is a structure, then using
isDefined("request.x.y.z")
is faster (mechanically) and easier than using
structkeyexists(request,"x") and isstruct(request.x)
and structkeyexists(request.x,"y") and isstruct(request.x.y)
and structkeyexists(request.x.y,"z")
and when the variable is well scoped in an isdefined() call
isDefined("variables.x.y.z") = good
isDefined("x.y.z") = bad
the likelyhood of namespace conflicts is minimal at best.
