There is a plugin which creates additional columns in “oxarticles” table and have some data for each article created by the plugin.
When i go to the “Administer Products > Products” and press “copy article” button it also copies that data created by the aforementioned plugin.
What i want to know is which part in this code in ArticleMain.php controller in core files is responsible for copying that data too? So when i extend this functionality via separate plugin , i could remove it.
PS: don’t know why sharing code snippets shows “403 error” that’s why sharing it via link.
