Comment 2 for bug 733089

Thanks for reporting this, I have tested as your description for nested o2m and faced the same problem.

I have tested with,
Sales > Configuration > Pricelists >New (Create new record) > New (Pricelist Version) > New (Products Listprices Items)
- Now first click on button "New" it saves the parent record but could not open next form And it opens after second click.

So, I have fixed this problem with revision number 4635 in dev branch like,
lp:~openerp-dev/openobject-client-web/trunk-bug-733089-jra .
