Comment 6 for bug 733089

Hello NOVOTRADE RENDSZERHÁZ,

Your patch as #4 (in which my changes are reverted) is not correct for nested o2m case, Its create a problem to load new o2m form.

Please try and check the behaviour as under,

Sales > Configuration > Pricelists > New (Products Price List)> New (Pricelist Version) > New (Products Listprices Items).

There should be open New form of Products Listprices Items on First click only.
But its save the parent record and do nothing for expected New Form open Because,
it does not find the value of terp_id, terp_model, terp_view_mode, etc..

So that changes are needed and Yes after that changes in revision 4566, the problem faced with only view_mode which is solved in sma's branch as #5.

So, both changes are needed for the nested o2m case and it works fine.

Thanks !
