You should pass the session-scope component into each individual method call on the app-scope component that needs it, but never storing the session-scope component in an instance variable. That'll keep your app-scope components session-neutral.
If you find that every method (or at least the vast majority) needs access to the session scope object, then you might consider a carefully constructed break in encapsulation. I.e. a getSessionObject() method inside your app-scope components (probably in a shared superclass, if you have one) that the app-scope cfcs can call to retrieve the session-scope object as needed. The fact that the app-scope components need a session-scope object and access it directly is a break in encapsulation, but by wrapping the break into a single method (so there's only one place that the break exists), you greatly reduce the negative effects that the break creates. <cffunction name="getSessionObject" access="private" output="false" returntype="path.to.my.session.object"> <cfreturn session.myObject /> </cffunction> It's definitely not a perfect solution, but it is one that works without requiring a huge amount of code refactoring if you have to band-aid an already existing application, and don't want to have to go add a new parameter to every method, and every method invocation. API changes are ridiculously expensive, so a little hackishness is allowed to avoid them. cheers, barneyb On 6/11/05, Johnny Le <[EMAIL PROTECTED]> wrote: > Hi, > > I have several components that are the same for all users throughout the > site.
