It isn't as though we just had a huge patch about this or anything. SCOPE. YOUR. VARIABLES.

What, I liked myVarFOo now its my.session.var.foo Why did I need to know where it should be? Adobe has always just made it magic!

Gesundheit.

I thought it was google zeitgeist for a second... Doh! https://trends.google.com/trends/

When invoking a component is there a scope for the return variable?

you can do a returnVariable to move it in the variables scope

Excellent!

Note, you can put it in other scopes besides variables, it just defaults to the variables scope if you do not define it.

So you would specify, for example, returnVariable="application.MyReturnVariable"?

Yes!
