Assume that model A has a computed field G that depends on both fields
F1 and F2. Assume that model B inherits from A (_inherits). When G is
computed during an onchange, it must use the form values for all its
dependencies F1 and F2. Before this commit, only the field triggering
the onchange was assigned on the parent record (see (*) below.)
record parent
--- ------------+-------------+------------
initial state | F1=0, F2=0 | F1=0, F2=0
assign F1=1 | F1=1, F2=0 | F1=1, F2=0
assign F2=2 | F1=1, F2=1 | F1=0, F2=1 (*)
The commit also includes another patch: when assigning the parent
record, the ORM determines the dependent records (in this case, the main
record in the onchange). If the delegate field (many2one from B to A)
has an inverse one2many field, the ORM uses that field to determine
dependent records. However, in the case of a new record, that field is
not in cache, and its value is determined to be... empty! The patch
consists in "fixing" the value of that field when we determine the
parent record (when the delegate field is accessed.)
