Hi all. Im using get part of url to filter my collection using query parameters. The only issue is that the query parameters will disappear when I change views, but I want to save that value to the user. So how can I save the query parameter value and only change it in the user table if the value changes and is not null (in other words only if there is a new query parameter value that isnt null)?

You’ll need a custom action with a Set Column action and a condition on that custom action that will only set the column value when the value does not match and is not empty.
