Comment 10 for bug 724525

the reason why its won't fix even after fix is:
we can't accept the changes which are done in order to fix this bug(not for trunk-addons) as these changes are for checking some relations of sale in purchase module(btw it was not by me),
I can make this as confirmed back (not a problem), but still we can't change (easily) a single line of code in addons
(yes, we can change, as did in branch attached, but its not a generic and acceptable change
why because, think of the others who don't have sale installed, and still we are checking for a field of sale in purchase),
this can be done in extra-addons by making a new module that depends on sale and purchase so when we install that module we have both modules installed and our solution can play a role without any problem,
as said in comment #8 please report another bug for workflow as even this bug is confirmed(!) we can not say the problem of workflow is accepted or not, so its better to separate both the problems..
Thanks
