Give me a comment about woocommerce.

I made a custom item field for woocommerce order.

on wp_woocommerce_order_itemmeta, I added meta_key '_line_pinlist' using

wc_add_order_item_meta( $item["id"], '_line_pinlist', $meta_pin_list )

I added this function on update_status() of class-wc-order.php.

this function is called on

if ( 'completed' == $new_status->slug ) { }

flow.

when I click 'complete' button _line_pinlist was wrote on database with this function call.

sample: '383', '46', '_line_pinlist', '13906549391125710', '46' (wp_woocommerce_order_itemmeta)

but when I receive email this field is empty.

on [url removed, login to view], I already added one more column like

<td style="text-align:left; vertical-align:middle; border: 1px solid #eee;"><?php echo $item['line_pinlist']; ?></td>

when I put the debug at the end of line like

<tr>

<td colspan="4">

<?php echo var_dump($items);?>

</td>

</tr>

it doesn't contain any line_pinlist. (but db field is already filled up)

I don't know well about woocommerce function lifecycle.

maybe, after email sending out, status update called or $items is cached before status update.

this issue eating my time. anyone who knows well about woocommerce, please teach me how to solve this issue.
