pseudo constructor?
I think, you mean defined as local variables to that component.
The problem is that Coldfusion 8, has to reset that instantiation for
mappings and custom tags each and every time the application.cfc is
instantiated. By placing these in the onApplicationScope, means that they
are no longer available the next time the Application.cfc is created.
Hence by placing them in the local variables for the component, and that
would be the this scope, allows for that re initialisation of the variables
each and every time. I don't like that idea, but there is a valid reason for
it to be this way.
The reason it complains when it gets to the line
CreateObject('component','components.security')>
Means that you have set them to the Application scope, and not the this
scope. So the mapping and directory components doesn't actually exist as far
as Coldfusion is concerned.
Hope that makes more sense.

Oh I forgot... this.mappings is only going to work in the psuedo
constructor.
