New line disappear when click on cancel after editing in one2many
Create a new supplier shipment, select supplier then select an incoming move (using the "+" on the search widget - add/remove on One2Many). Then double-click on the line to edit. On the edit form click on cancel. Line is still on the screen. Then click to receive/save supplier shipment, line will disappear but state is received without line.
Same behaviour applies to also to supplier invoices (i think to all one2many with an add_remove attribute). But in the case of supplier invoices, i'm doing the same scenario but instead of saving, i'm clicking on "Post"... line disappear and invoice is posted without line ! (i think it's another bug to prevent to post or validate an invoice without line)
