base_sale_multichannels : auto-reconcile stucks the workflow

Hi,

This bug report is for record and if in case of someone has already fixed such issue or had a great idea.
I put my bug report in the magentoerpconnect project because I think it'll have more visibility than in extra-trunk.

I already lost my day on this bug so I'm crazy and depressed about it.

As you can see, I had to comment a feature while we do not have any solution :
http://bazaar.launchpad.net/~openerp-commiter/openobject-addons/trunk-extra-addons/revision/5660

The issue appears when we use the auto-reconcile and post-paid on a base sale payment type.

A scenario :
 - Import an order from magento, it has one product to deliver, it is already paid on magento
 - The delivery order is created
 - A customer payment (voucher) is created
 - I deliver all the delivery order
***
 - According to my base sale payment type configuration, the created invoice is automatically opened
 - The previously created payment is automatically reconciled with the invoice
***
The steps between the stars are done in an inherit of action_invoice_create()

When I check my sale order, I see it is :
 - Paid
 - Delivered
But the workflow of my sale order stay in "progress".

Now a second scenario, also post-paid but I do not check the auto-reconcile :
A scenario :
 - Import an order from magento, it has one product to deliver, it is already paid on magento
 - The delivery order is created
 - A customer payment (voucher) is created
 - I deliver all the delivery order
***
 - According to my base sale payment type configuration, the created invoice is automatically opened
***
 - I reconcile the previously created payment with the invoice (I call the method auto_reconcile() to be sure that the problem don't come from this method)

The steps between the stars are done in an inherit of action_invoice_create()

When I check my sale order, I see it is :
 - Paid
 - Delivered
But the workflow of my sale order is well "done".

The problem comes from the fact that action_invoice_create is an action on the workflow activity "invoice" of the workflow "sale.order.basic".

It think that it does not accept that the sub-workflow (so the invoice one) changes its state directly from the action of the activity "invoice". It should be done afterwards only.

The activity "invoice_end" of the sale order workflow is never called, it stays in "invoice" even if the "invoice" workflow is complete.

I don't know if it is something that can be changed (corrected? bug or feature? ;-)) in the workflow engine, or if we can find a way to reconcile the payment with the invoice later.

If someone find a solution, even if it is just a beginning, I will be so grateful!
