Comment 1 for bug 1226086

Hi again !

I searched a little about my problem and I found one weird behaviour.

After upgrade, in ir_ui_menu, all my news items are without parent_left and parent_right values.
in 7.0, 'ir.ui.menu' is _parent_store. (Not in 6.1).

It appears that during the migration the compute of parent_left & right works for existing values but not for news.
[LOG during migration, at the beginning] : Computing parent left and right for table ir_ui_menu...

This 2 lines fix the bug but it's just a workaround. (I exactly don't know if the problem comes from openobject or openupgrade).
Maybe the problem can occur for other new _parent_store model too ...

### Workaround :
# In the end of the migration (in the file "deffered_70.py" for exemple) :
my_obj = pool.get('ir.ui.menu')
my_obj._parent_store_compute(cr)
