Polymorphic classes in workflow?

[Alon Raskin]

Seems like an unnecessary work around (but I will take it). If only SAP allowed proper polymorphic behaviour....

There there, actually an answer to your problem may be at hand - you can
enable a type NN (Not Defined) as a container element type as of some
service pack.
This is supposed to work, though I still get no end of binding-related
errors. In my case I'm trying to restrict things further than IF_WORKFLOW,
e.g. IF_WF_INVOICE with a number of associated classes for different
purposes.
