weird.
if i had to venture a guess, i'd say that BOTH session.nameObj and
variables.namePointer are references to the same underlying object. When
you call structDelete(session,"nameObj") you are deleting a pointer
(hence the error when you try to reference it later) but the other
pointer still exists...
this is, as mentioned, just a guess...

Subject: [CFCDev] CFC Assignment Query
If CFCs are copied by reference [as the output at line 8
suggests] then how come I can still reference an object [line 10] once
it has been deleted [line 9]? I would expect line 10 to throw an error
but it doesn't, however, an attempt to reference session.nameObj at the
same place does.
Can anyone help me understand what I am seeing?
1. <cfapplication sessionmanagement = "true">
2. <cfset session.nameObj = createObject('component',
'nameComponent').init()>
3. <cfset session.nameObj.setName("Elaine")>
4. <cfoutput>
5. <cfset variables.namePointer = session.nameObj>
6. #variables.namePointer.getName()#<br>
7. <cfset session.nameObj.setName("Richard")>
8. #variables.namePointer.getName()#<br>
9. #structDelete(session, "nameObj")#
10. #variables.namePointer.getName()#<br>
11. </cfoutput>
