Prevent save model when clicking on a button that raises a wizard
I have a problem in my module... I need to save my model (lets call this Model_A) after filling a form raising for a wizard. The explanation is: I have a module that has a button which raises a wizard , so, when i press that button it saves the Model_A before and then raises the wizard. The problem is that i need to fill some fields in the wizard form, save it, close the wizard, and after that save Model_A by clicking on the save button. Any suggestion? I already tried by overriding the create function and returning False, None, an empty dictionary... I tried the solution given on the below link  but it doesn't work for me. Iam working with Odoo V8.
