WPML - Cart item data custom Fields don't update when switching language - php

Question

I am using Woocommerce plugin with WPML Multilingual plugin, and I simply can't get to work like I would expect.
My products have serveral Custom Fields that I need to display in the cart, Checkout, Order views and emails notifications.
The Fields are displayed correctly on frontend but when I switch the language the data from sessions are not updated.
How does WPML handle the extra data?
Is there a way to get this to work, that the data update when i switch the language?
Here is my code:
add_filter( 'woocommerce_product_data_tabs', 'mbextra_product_data_tab' , 99 , 1 );
function mbextra_product_data_tab( $product_data_tabs ) {
$product_data_tabs['mbextraproducttab'] = array(
'label' => __( 'EXTRA', 'mbg' ),
'target' => 'mbextraproductdata',
'class' => array();
);
return $product_data_tabs;
}
add_action( 'woocommerce_product_data_panels', 'mbextra_product_data_fields' );
function mbextra_product_data_fields() {
?>
<div id="mbextraproductdata" class="panel woocommerce_options_panel">
<div class="options_group">
<?php
woocommerce_wp_textarea_input(
array(
'id' => 'company',
'label' => __( 'Company', 'mbg' ),
'placeholder' => 'Company Adress here',
'desc_tip' => 'true',
'description' => __( 'Enter Company Adress here', 'mbg' )
)
);
?>
</div>
<div class="options_group">
<?php
woocommerce_wp_textarea_input(
array(
'id' => 'shortdescription',
'label' => __( 'Short-Description', 'mbg' ),
'placeholder' => 'Enter some short info',
'desc_tip' => 'true',
'description' => __( 'Enter Short description here', 'mbg' )
)
);
?>
</div>
</div><!-- #extraproductdata Tab -->
<?php
}
add_action( 'woocommerce_process_product_meta', 'mbprocess_product_meta_fields_save', 99 );
function mbprocess_product_meta_fields_save( $post_id ){
// if set > save the fields
$company = $_POST['company'];
if( isset( $company ) )
update_post_meta( $post_id, 'company', esc_attr( $company ) );
// if set > save data to post_meta
$shortdescription = $_POST['shortdescription'];
if( isset( $shortdescription ) )
update_post_meta( $post_id, 'shortdescription', esc_attr( $shortdescription ) );
}
add_filter( 'woocommerce_add_cart_item_data', 'custom_product_field', 10, 3 );
function custom_product_field( $cart_item_data, $product_id, $variation_id ) {
$shortdesciption = get_post_meta( $product_id , 'shortdesciption' , true );
$company = get_post_meta( $product_id , 'company' , true );
if( !empty( $shortdesciption ) )
{
$cart_item_data['shortdesciption'] = $shortdesciption;
}
if( !empty( $company ) )
{
$cart_item_data['company'] = $company;
}
return $cart_item_data;
}
add_filter( 'woocommerce_get_cart_item_from_session', 'mbget_cart_item_from_session', 10, 3);
function mbget_cart_item_from_session( $cart_item_data, $cart_item_session_data, $cart_item_key ) {
if ( isset( $cart_item_session_data['shortdesciption'] ) ) {
$cart_item_data['shortdesciption'] = $cart_item_session_data['shortdesciption'];
}
if ( isset( $cart_item_session_data['company'] ) ) {
$cart_item_data['company'] = $cart_item_session_data['company'];
}
return $cart_item_data;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );
function render_meta_on_cart_and_checkout( $cart_data, $cart_item ) {
$data = array();
if( !empty( $data ) ) {
$data = $cart_data;
}
if( isset( $cart_item['shortdesciption'] ) ) {
$data[] = array(
'name' => __( 'Stuff', 'mbg' ),
'value' => $cart_item['shortdesciption'] );
}
if( isset( $cart_item['company'] ) ) {
$data[] = array(
'name' => __( 'Company', 'mbg' ),
'value' => $cart_item['company'] );
}
return $data;
}
Thanks

YES you should need to destroy the cart session or to remove all cart items when switching language. But this kind of case never really happen:
As it is NOT really a customer behavior, adding items in cart (for some language) and then switch to another language before checkout for example.
So this should not be really a problem. This is just the behavior of a developer that is testing an e-commmerce in all possible ways, isn't it?
