An alternative to wrapping in a <cftry> block is <cfparam>, something like:
<cfparam name="rootObject.Get_ObjectName" default="undefined!"/>
<cfif isSimpleValue(rootObject.Get_ObjectName)>
<!--- it's undefined! --->
<cfelse>
<cfset theValue=rootObject.Get_ObjectName().Get_Value()/>
</cfif>
I use a similar mechanism to cope with accessing elements in sparse
arrays (though I default to #server.undefined#, which is a Java object I
create for just this sort of purpose); it should work for your problem too.
