Odoo - prevent button from closing wizard

Question

I have a transient model that serves as a dialog. In my form view I have a button like this:

<footer states="partnerId">
   <button name="check_tax_id" string="Tovább" type="object"/>
</footer>

The button invokes this function (I can confirm it actually invokes):

@api.one
    def check_tax_id(self, context=None):
        self.state = "partnerDetails"

        return None;

My problem is that the dialog window is closed immediately once I click this button! What am I doing wrong?

yesterday I bumped on this same issue. I needed to show a button to do something without submitting the whole wizaard. I worked around it by not using a button at all. It's pretty simple and effective. What you need:

1. a boolean flag in your wizard model
2. an onchange attached to the flag (that replaces you sumbmit function)
3. replace the button in the view w/ the flag w/ invisible="1" and a label to be styled as a button

Here's the code:

source_it = fields.Boolean(string='Source')
[...]
def action_source(self):
    # do stuff

@api.onchange('source_it')
def onchange_source_it(self):
    if self.env.context.get('sourcing_now') or not self.source_it:
        return
    self.action_source()
[...]
<label for="source_it" class="pull-left btn btn-success" />
<field name="source_it" invisible="1" />

The trick works because when a label has for attribute is going to act like the checkbox itself, so if you click on the label you are actually switching the checkbox.
