[Erp5-dev] Changing workflow association and restoring document's workflow state

[Łukasz Nowak]

Hello,

I have to change some important workflow associations (eg. which
provides simulation_state). I need documents to be moved to same state,
as they had from association from former workflow.

I've experimented a little with removing workflow association from
portal type, and I've seen that in Base_viewHistory it is possible to
fetch history of workflow transitions from old association - even
reindexing object do not remove this history.

I'll go with below scenario:
 - create my own workflows (ventis_workflow)
   - add special transition from starting state to all possible states
   - ventis_workflow will have all states as original_workflow
 - remove association from old workflow (original_workflow)
 - fetch actual state from original_workflow's history which
hasn't been deleted
 - jump into fetched state using transition from ventis_workflow

Is my scenario good enough? I'll try to test it as best as possible,
but any clues are welcome.

Regards,
Luke
