Close fiscal year wizard usable for a multi company database

The "Close a fiscal year" wizard doesn't allow to do a closure in a multi company database.

People normally use record rules to show only the account of their company, and that's a problem when this wizard wants to access an account of another company. So, I added these lines in the wizard to access only the account from the company of the user and now I can do my closure in a multi company database.

Maybe there is already a solution in OpenERP 5 like that or maybe there should be one. This is usable too for a single company database.
