How can I call a wizard in a return of a function? 

This is the first wizard that appears: 

class get_ticket(osv.osv_memory):    
    _name = 'get.tickets.wizard'    

    def _tickets_control(self, cr, uid, context=None):        
        active_ids = []        
        partner_ids = {}        
        for active_id in context.get('active_ids'):            
            active_ids.append(active_id)            
            for partner_id in self.pool.get('tickets').browse(cr, uid, active_id, context=context).partner_id:                
                partner_ids[partner_id.id] = partner_id.id        
        if len(active_ids) <= 1:            
            self.display_error_message(cr, uid, 'You have to select more than 1 tickets.')            
            return False 
        elif len(partner_ids) > 1:            
            self.display_error_message(cr, uid, 'You have selected 2 or more tickets of different partners.')
            return False        
        return True    
    
    def display_error_message(self, cr, uid, error, context=None):        
        view_id = self.pool.get('ir.model.data').get(cr, uid, 'get_ticket_wizard', 'close_wizard_form_view', context=context) 
        view_id = view_id[0]        
        return {            
            'name': _("Error"),            
            'view_type': 'form',            
            'view_mode': 'form',            
            'view_id': view_id,            
            'res_model': 'close.wizard',            
            'type': 'ir.actions.act_window',            
            'target': 'new',            
            'context': {'error': error},        
    }    

    _columns = {        
        'ticket_id': fields.many2one('tickets', string='Ticket to keep'),        
        'control': fields.boolean(compute='_tickets_control'),    
    }    

    def onchange_get_tickets(self, cr, uid, ids, context=None):        
        active_ids = []        
        for active_id in context.get('active_ids'):            
            active_ids.append(active_id)        
        return {'domain': {'ticket_id': [('id', 'in', active_ids)]}}    

    _defaults = {        
        'control': _tickets_control,  
    }

And this is the wizard that I want to call (that has the function like an error message and close the wizard before and this [this I don't know if really does it]): 

class close_wizard(osv.osv_memory):    
    _name = 'close.wizard'    

    def _display_error(self, cr, uid, ids, context=None):        
        return context.get('error')    

    def _close_window_wizard(self, cr, uid, ids, context=None):        
        return {'type': 'ir.actions.act_window_close'}    

    _columns = {        
        'error': fields.char(string=''),    
    }    

    _defaults = {        
        'error': _display_error,    
    }

And this is its view: 

<!-- ********** Form view of close wizard ********** -->
<record model="ir.ui.view" id="close_wizard_form_view">    
    <field name="name">close.wizard.form</field>    
    <field name="model">close.wizard</field>    
    <field name="arch" type="xml">        
        <form string="Error">            
            <group>                
                <field name="error"/>            
            </group>            
            <footer>                
                <button string="Accept" name="%(_close_wizard_window)d" type="action" class="oe_highlight"/>         
            </footer>        
        </form>    
    </field>
</record>
<!-- ********** Option get tickets in menu 'More' ********** -->
<act_window id="close_wizard_action"            
    multi="True"            
    key2="client_action_multi"            
    name="Error"            
    res_model="close.wizard"            
    src_model="get.tickets.wizard"            
    view_mode="form"            
    target="new"            
    view_type="form"/>
