Check the "layout.cfg.xml" of your layout. There is a attribute named "feedbackAttributeNr". You can configure the model attribute for the feedback mail address.
Many thanks for your help.
I configured the <feedbackAttributeNr> to <creator of the model>. Feedback button is now working but only the model name appear within the subject of email. We need a link to that model within feedback email whenever end-user clicks on feedback button. How we can achieve this?
to change the function programmatically
for your question of how to configure feedback by email there is a tutorial by Mr. Ismael Shameem Etowar
If you import your Aris users from an LDAP directory service you would need to pull their email addresses and place them in the Aris user attribute too.
