Hi i have a button and this is how i define it.

odoo.define('button_near_create.tree_button_create_quotation', function(require) {
    "use strict";

    var ListController = require('web.ListController');
    var ListView = require('web.ListView');
    var viewRegistry = require('web.view_registry');
    var rpc = require('web.rpc');
    var core = require('web.core');
    var Dialog = require('web.Dialog');
    var _t = core._t;

    var TreeButton = ListController.extend({
        buttons_template: 'button_near_create.button.quotation',
        events: _.extend({}, ListController.prototype.events, {
            'click .open_wizard_action_subscription': '_OpenWizardTree',
        }),

        _OpenWizardTree: function () {
            var self = this;

            // Kaydetme butonunu bul ve tıkla
            var saveButton = this.$buttons && this.$buttons.find('.o_form_button_save');
            if (saveButton && saveButton.length) {
                saveButton.click();
            }

            // Kaydetme işleminin tamamlanmasını bekle ve ardından devam et
            setTimeout(function() {
                var domain = [['products', '!=', false]];

                rpc.query({
                    model: 'et.subscription',
                    method: 'search',
                    args: [domain],
                    fields: ['id']
                }).then(function(ids) {
                    if (ids.length === 0) {
                        Dialog.alert(self, _t('No records found with products.'));
                        return;
                    }
                    console.log('Subscription IDs:', ids);
                    rpc.query({
                        model: 'et.subscription',
                        method: 'renew_selected',
                        args: [ids], // args kullanarak ids'yi parametre olarak iletme
                    }).then(function(result) {
                        console.log('Result:', result);
                        if (result && result.type === 'ir.actions.act_window') {
                            self.do_action(result);
                        } else {
                            Dialog.alert(self, _t('An error occurred while creating the quotation.'));
                        }
                    }).catch(function(error) {
                        console.log('Error:', error);
                        var errorMessage = _t('An error occurred');
                        if (error.message && error.message.data && error.message.data.message) {
                            errorMessage = error.message.data.message;
                        }
                        Dialog.alert(self, errorMessage);
                    });
                }).catch(function(error) {
                    console.log('Error:', error);
                    Dialog.alert(self, _t('An error occurred: ') + JSON.stringify(error));
                });
            }, 0); // Kaydetme işlemi için 1 saniye bekle
        }
    });

    var ContactCreateTreeController = ListView.extend({
        config: _.extend({}, ListView.prototype.config, {
            Controller: TreeButton
        }),
    });

    viewRegistry.add('button_in_tree_subscription', ContactCreateTreeController);
});

<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
   <t t-extend="ListView.buttons" t-name="button_near_create.button.quotation">
       <t t-jquery="div" t-operation="prepend">
               <button t-if="widget.modelName == 'et.subscription'"
                       class="btn btn-primary open_wizard_action_subscription oe_highlight"
                       type="button">Create Quotation (Renew)</button>
       </t>
   </t>
</templates>

and renew_selected function has a return value like that

def renew_selected(self):
        sale_orders = [1,2,3]
        tree_view_id = self.env.ref('sale.view_quotation_tree_with_onboarding').id
        form_view_id = self.env.ref('sale.view_order_form').id

        return {
            'name': 'Sale Orders - Specific',
            'type': 'ir.actions.act_window',
            'view_mode': 'tree, form',
            'res_model': 'sale.order',
            'domain': [('id', 'in', sale_orders)],
            'target': 'new',
            'views': [(tree_view_id, 'tree'), (form_view_id, 'form')],
        }

sale.order has id(1,2,3) values
tree_view_id and form_view_id is coming correctly. But this function opening form view every time.
When i remove ‘form’ from view_mode and views, its giving me error

UncaughtPromiseError > TypeError

Uncaught Promise > action.views is undefined

TypeError: action.views is undefined
    _preprocessAction@http://localhost:8069/web/assets/773-4de1bdd/web.assets_backend.min.js:10887:57
    doAction@http://localhost:8069/web/assets/773-4de1bdd/web.assets_backend.min.js:10994:170
    

Any idea why its not opening tree view ?

I tried to create a new tree view but it didnt worked also.
