After further investigations (thanks Chrome Developer Tool and JavaScript debugger), I finally found the mechanism behind the magic.

Instead of:


 Replaced with:

var controller = self.get_active_view().controller;

Complete code below:

Usage in templates:

<field name="One2many_name" widget="one2many_selectable" action="server_action" callback="javascript_callback>

If defined, "server_action" will be RPC called and executed by server
If defined, "javascript_callback" will be executed client side after "server_action" is executed server side,
if also defined. "javascript_callback" will be sent results returned from "server_action" if any.

odoo.define('web_one2many_selectable_10.form_widgets', function (require) {
"use strict";

var core = require('web.core');
var _t = core._t;
var Model = require('web.Model');
var FieldOne2Many = core.form_widget_registry.get('one2many');

function executeFunctionByName(functionName, context /*, args */) {
var args = Array.prototype.slice.call(arguments, 2);
var namespaces = functionName.split(".");
var func = namespaces.pop();
for (var i = 0; i < namespaces.length; i++) {
context = context[namespaces[i]];
return context[func].apply(context, args);

var One2ManySelectable = FieldOne2Many.extend({
template: 'One2ManySelectable',

events: {
'click .web_one2many_selectable': 'button_pressed',

multi_selection: true,

// Retrieve options from caller template to have them available in the widget 'One2ManySelectable' template
init: function () {
this._super.apply(this, arguments);

// Default options
this.options = {
caption: 'Apply',
action: null,
callback: null

// User defined options from field attributes in caller template
if (arguments[1].attrs.hasOwnProperty('options')) {
this.options = JSON.parse(arguments[1].attrs.options);

// Translate caption
this.options.caption = _t(this.options.caption)

start: function () {
this._super.apply(this, arguments);

// Catch button pressed event, collect IDs, call action server side, then callback client side if defined.
button_pressed: function () {
var self = this;
var selected_ids = self.get_selected_ids_one2many();
if (selected_ids.length === 0) {
this.do_warn(_t("You must choose at least one record."));
return false;

// If an action was defined in template, let's call this action server side
if (this.options.action) {
/* Here is a python example function to parse the selected objects

def your_action_name(self):
for record in self:
print record

var model_obj = new Model(this.dataset.model);
model_obj.call(this.options.action, [selected_ids], {context: self.dataset.context})
.then(function (result) {
if (self.options.callback) {
// If a callback was defined in template, let's call this callback client side with
// results from server call above.
executeFunctionByName(self.options.callback, window, result);
} else {
// Else simply refresh the display for the selected records
var controller = self.get_active_view().controller;

// Collect the object IDs for checked checkboxes
get_selected_ids_one2many: function () {
var ids = [];
this.$el.find('td.o_list_record_selector input:checkbox:checked').closest('tr').each(function () {
return ids;


// Register this widget
core.form_widget_registry.add('one2many_selectable', One2ManySelectable);

// Make the widget available for other add-ons
return {
One2ManySelectable: One2ManySelectable
