[Erp5-dev] Modifying existing workflow history

[Jacek Medrzycki]

Hi.

Is there any way or hack to modify existing workflow history, in
particular values of transition variables such as 'comment'?

Sometimes our client wants us to modify wrong data entered by their
operators. We easily can do that if the data is standart property, but
not if it is in workflow history.

Regards
J.

It's because of the way data is stored in the workflow_history property.
You should take a look at this page I recently created on the wiki:

http://wiki.erp5.org/UnderstandingPersistency

Precisely, it takes workflow_history as an example.

Workflow history is intended to be read-only. You can say to your
customer that if workflow history can be modified, then the system no
longer provides traceability.

Accountants are usually very happy that the workflow history is
read-only (ie. to prevent someone from changing a transaction without
leaving a trace).
Security people are also very happy that workflow history is read-only.

So, if you need something which needs to be modified, consider using
something else (ex. subobjects of the current document).
