Hi, 

I have made some changes to the stock.picking model, specifically inheriting the button_validate code, but clicking the button no longer does anything, so I removed all changes, but still It does nothing.

I made sure there are no other modules redefining button_validate (other than stock & stock_landed_costs modules), is-there some Odoo behavior that stops the stock from validating without throwing any sort of errors ? 

All I get right now (in the browser network monitor) is a call to call_button ( /web/dataset/call_button) with the form parameters & button_validate as method, the response is as simple as  {"jsonrpc": "2.0", "id": 124832555, "result": false}

I get also 3 read calls ( /web/dataset/call_kw/stock.picking/read) and no javascript console error.

Thank you
