I created a custom tab in customer edit page in admin panel. It works perfectly, but I want to position the tab, so I tried to edit the customer_index_edit.xml
file like below by adding:
<action method="addTabAfter">
<argument name="after" xsi:type="string">wishlist</argument>
</action>
but it's not working and throwing an error:
[2017-10-09 05:56:42] main.CRITICAL: Invalid method vendor\module\Block\Adminhtml\Edit\Tab\Rewardpoints::addTabAfter
My customer_index_edit.xml file is below.
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left"
xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
