Declarative action does not appear (as buttum) on the list view portal component

[andreadigiu]

using SN Studio, I have created a portal, ceated a scrtach page , inserted a list view component configured to show records of one my table  . The list view shows correctly the records.

Created a declarative Action (serve script) with label "Confirm" for list model, mapped on my UI Action Configurayion (created new) , mappedn on a UI property page (cerated new) .

NO BUTTONS appears on my list view header!! Tried everithing!

a "confirm" button was supposed to appear on the list view header ......

Any kind of hint please?

Hi @andreadigiu 
I've had this where sometimes these updates don't update automatically - have you tried clearing your cache or logging out of your instance and back in? 

A couple of other things to check:
Is your Declarative Action Assignment record enabled for the correct table and experience:

Your Declarative action type - is the action type List Header? 
Do you have any scripts or conditions that could be hiding it? 
Is your UI action related to the declarative action & is the action type also something that supports List Header? 
Do you have an associated Declarative Action Policy to handle the actions - and is it related to the correct table?

There is a really great guide here: Declarative Actions in ServiceNow: The COMPLETE Guide

Hi Hanna, thank you very much for the support,

I logged out/in many times.

Your Declarative action type - is the action type List Header?  yes it is
Do you have any scripts or conditions that could be hiding it? the page is from scratch should not exits restriction
Is your UI action related to the declarative action & is the action type also something that supports List Header?  no,do i need also a UI action?? is not implicit in the Declarative action (where i put the script)??
Do you have an associated Declarative Action Policy to handle the actions - and is it related to the correct table?  do you mean an UX Action Configuration?? yes ,below the screen shot..I have not file of type "polocy" 

here's some scrren shots:

follows the Assigment Action, i stil don have set a script but the button should appear anyway...the action is a list type ( exactlu a Actin Model=List) ....it's associated with my application not a specific experience..

Follows the Acction COnfiguratio, the xxx-yat-confemra appears in the list action tab

this is the property page ...
