[Post Construct] being run when service classes inherit from a class having Post Construct

As I have several areas of services for an AIR application I've chosen to split up my initial service class into sub classes which inherit
from a base class which has a meta tag [Post Construct].
As all being service classes they're mapped as 'mapSingletonOf'.

Now, the problem I detect is that the [Post Construct] seem to be run whenever the instansiation of the child classes occur
and it seems to 'corrupt' the singleton state of the parent?!?

Any one experienced similar behavior or do I simple do something wrong?

Kind Regards

    That is the behavour one would expect to happen when creating subclasses.

    In the child class, override the method that has the [Post Construct] tag and make it do nothing.

    True, that the parent class will be instantiated, but as being mapped as mapSingletonOf I would expect the container to return the already instantiated object,
    hence, Post Construct wouldn't be run.
    And the real problem is that I seem to get a new instance of the parent class.

    I might try go for Composition instead :-)
