[Zope-CMF] DCWorkflow innards. Why does the default state not honour automatic transitions??

[robert rottermann]

Thanks for your answer,
When I copy a an existing Document the copy is treated like a newly creat=
ed=20
one and gets the initial state assigned. This is OK.=20
However since the Document is not really new I want it to aquire a state=20
different from the initial one. This transition could be done automatical=
ly=20
if only the workflow machinery would not stop short.

I can solfe my problem with a script within a transaction. But I would th=
ink=20
it more elegant if DCWorkflow would do it.

So my real question is wy does DCWorkflow show such a behaviour. Would=20
honouring automatic transactions have unwanted side effects?
