When are custom component parameters enumerated?

Hi,

I have been doing some tracing around some components I have created and I have found that the [Inspectable] parameters are not read until some time after the constructor has been processed.

That is I have traced in the constructor several parameters and they are null
and then traced the same parameters in the addedtostage event and they are populated?

Does anyone know the order of enumeration for components.

Regards

Matt
