[Forums] Unable to pass the field names

Hi 

I am unable to pass field names and it always shows example field names as drop downs in the field drop down.

I am currently using 9.x version and i have installed the component and example works perfectly fine. 

i have cloned the UserList_InitializeValues in actions and passing the field names to the advanced filter widget. But i am not seeing my field names in the drop down and it always shows example field names like name, company, email

Is there anything i am missing to integrate into my screen ? any help is appreciated. thank you.
