For the display I have: <cfinvoke component="report.facade" method="getSummary" returnvariable="aStruct"> </cfinvoke> <cfloop query="aStruct.query1"> </cfloop> For certain roles that data will reside in application scope and others in session....I felt I needed to do this because the app is very data intensive.

It uses reference semantics. However, it's not really good practice to have CFCs store results in shared scopes - CFCs should be independent of their environment. However, if the CFC stores things in session scope - why bother returning them at all? Why not just let the caller access session.stuff directly? > <cffunction name="getAccounts"> You should add returntype="query" for extra validation. > <cfquery name="session.test"> > SELECT * FROM BLAH > </cfquery> > <cfreturn session.test> > </cffunction> You'd be better off having the caller (only) know about the session scope and using a local variable inside the function: <cfset var test = 0/> <cfquery name="test"> SELECT * FROM BLAH </cfquery> <cfreturn test/> Then the caller would do: <cfinvoke component="accounts" method="getAccounts" returnvariable="session.aQuery"/> if you wanted it to stay in session scope (the query is not copied, only a reference to it, so this is fast). Or, if you just wanted a local copy: <cfinvoke component="accounts" method="getAccounts" returnvariable="aQuery"/> Note that since 'test' inside the function is declared with 'var', it will be a new copy for every invocation.
