I don't use the swf object you mention. In the render phase is ok to create
objects on the fly that will help you render a component. Scriptaculous way of
adding javascript in Seaside applications use and abuse from that. You can use
the wrapper as a dispensable thing that is initialized with fresh state (of that
dispensable thing). Note that this will be different from changing state of the
component itself. Think of a scriptaculous effect. It is created, configured
passed as paramenter and it only will last for that render.
If your wrapper is usable like that, then it would be perfectly fine to use one
on the fly. Check if is really justified to make that wrapper to be placed in an
inst var of your component. If not, remove it and use as if it where an effect
or whatever. 
If it really justified that every instance should be part of the component. It
will be considered (sub)state. In such a case I can understand your worry about
thinking better where to set the state.
