Title:
Subflow signal not received when it ends in the activity's python
action
Status in OpenERP Server:
Triaged
Bug description:
Hello,
I will try to explain this issue which is a bit tricky.
It probably doesn't occurs in the OpenERP addons, but it implies
limitations of the framework.
When a subflow ends within a python action of the activity, the
transition to the next activity is not triggered.
Let say I have inherited the method action_invoice_create of
sale.order in order to automatically open the invoice and reconcile a
payment directly when the invoice is created.
Something like that (simplified code of a real case in
base_sale_multichannels) :
class sale_order(osv.osv):
_inherit = 'sale.order'
def action_invoice_create(self, cr, uid, ids, grouped=False,
states=['confirmed', 'done', 'exception'], date_inv = False, context=None):
inv_obj = self.pool.get('account.invoice')
wf_service = netsvc.LocalService("workflow")
res = super(sale_order, self).action_invoice_create(cr, uid, ids,
grouped, states, date_inv, context)
for order in self.browse(cr, uid, ids, context=context):
if order.order_policy == 'postpaid':
for invoice in order.invoice_ids:
wf_service.trg_validate(uid, 'account.invoice',
invoice.id, 'invoice_open', cr)
inv_obj.auto_reconcile(cr, uid, [invoice.id],
context=context)
return res
sale_order()
class account_invoice(osv.osv):
_inherit = 'account.invoice'
def auto_reconcile(self, cr, uid, ids, context=None):
# code to automatically reconcile my invoice with an existing payment
account_invoice()
Here is a use case :
- I create a sale order in post-paid and confirm it -> delivery order is
created
- I create a payment for the amount of the sale order
- I deliver the packing -> the invoice is created with
action_invoice_create()
- Within action_invoice_create, the invoice is opened and reconciled => it
reaches the "paid" state
- Now, the sale order is :
* delivered
* paid
* BUT, it is still "in progress" instead of "done". The workflow state is
still "invoice"
-> the transition invoice to invoice_end triggered by subflow.paid has not
been triggered.
-> the workflow is stuck in an intermediate state
Here is a bug report on the module base_sale_multichannels where we
encounter this issue :
https://bugs.launchpad.net/magentoerpconnect/+bug/957136
The only solution I've found yet is to deactivate the auto-
reconciliation not to break the workflow.
I really tried to dive in the workflow code to find why this happens,
but I had have no success, I missed some keys to understand this
complex machinery.
If I can help to solve this problem, please ask.
Thanks
Guewen
