The reason you're getting a grey box from time to time is normally
because CFMX is encountering a compile time error rather than a runtime
error. In an live environment it would be very unusual to get that sort
of thing, because your templates have probably already all been compiled
and tested.
To answer your original question, when you do this:
<cfloop collection=#error# item="i">
<cfif i is not "generatedcontent">
#i# #evaluate("error.#i#")#<br>
</cfif>
</cfloop>
You are assuming that the error[i] will always be a simple value.
You could modify the code to look like this to avoid the problem.
<cfloop collection=error item="i">
<cfif i is not "generatedcontent">
#i#
<cfif isSimpleValue(error[i])>
#error[i]#<br>
<cfelse>
[:complex value:]<br>
</cfif>
</cfif>
</cfloop>
