Hi everyone,
I need to implement a modified version of the sale workflow, but instead of modifying directly the "sale.order.basic" workflow I want to create a new one by duplication.

Duplication works fino for the workflow object, for activities and transitions, but when I try to edit the new workflow in the visual diagram editor the page stops with a red message: Loading...
I tried to wait long but nothing. So I opened the server log and found this error:
[2009-09-02 11:52:16,993] ERROR:web-services:[01]: Traceback (most recent call last):

[2009-09-02 11:52:16,993] ERROR:web-services:[09]: IndexError: list index out of range

It could be becouse the duplication doesn't create a graph for the new workflow.

Anyone can help?
If this is a bug, how can i report it and where?

Hi,

when we duplicate complete workflow, duplication of records is successful in the database, where as the reference between the activities and transitions is not correct in the transition table. If their is no proper link, visual diagram editor cannot generate the diagram.
Duplication for workflow transitions will result in error, my suggestion would be to create new one by referring the existing.
