It is prudent to remember that TAGS hide a lot of what is actually going on
and example code is often not a solution but a snippet - just to show
syntactical relationships.
When we specify the RETURNVARIABLE in CFINVOKE we are telling it the
variable we want the data to go into. �The tag itself does the assignment
something like the following if we were writing it ourselves in "custom tag
code"....
<CFSET
rv=SetVariable("Caller.#Attributes.returnvariable#",theVariableBeingReturned)>
� � � � OR (in CFSCRIPT)
<CFSCRIPT>
SetVariable("Caller.#Attributes.returnvariable#",theVariableBeingReturned);
</CFSCRIPT>
What also needs to be remembered in the example from the book (despite the
typos) is that the component that it is calling is not defined. �It may
well be that the GETAUTH method does not return anything but actually sets
members inside the object itself. �All the other examples in the same area
imply there is no return value to assign. �Therefore, the code (in the
example - aside from typos) is probably correct.
So - it is only necessary to assign a result if your method actually
returns one. �It may not return one but may set a member in the object
itself.
So... in the example from the book.... it may be possible to do the
following (depending on the component definition - which we have not been
given).....
<CFSCRIPT>
� � � � // ......
� � � �corpQCFC.getAuth(argumentsCollention = tempStruct);
� � � � WriteOutput(corpQCFC.userAuthenticated);
</CFSCRIPT>
