can't show info/error message on the Workspace List page but can show on Simple list page

[ShuRiseUp2023]

Hi Community,

I was asked to add a button on the workspace List under Edit button. When select multiple records on the list, the button will be available and upon click, the selected records' state will change based on certain condition(if the state is in progress then it will change to Closed. Other state cannot be changed to Closed). I have created a before update business rule to show info/error message when the update is successful. Those info/error message can be shown on the simple list page but not the list page. In the List page, I added Update Multiple Records data source and added event mapping-Operation Succeeded then do 2 things: 1 refresh the list. 2, show a successful alert notification (the state updated successfully). When the button click it will trigger the Update Multiple Records data source to change the state to Closed. But strange thing is even the selected records cannot change state to Closed, the successful alert message is shown and list refreshed. 

So My question is:

1. Why the gs info/error message cannot show on the list page but show on simple list page.

2. Update Multiple Records data source how to define the operation succeeded? Even the update is failed, it's still triggered.

3. Is there other option to achieve my goals?

The before update business rule is: 

condition: state changes to Closed

Script: 

(function executeRule(current, previous /*null when async*/) {

    var preState = previous.getValue("state");

    if(preState!=20){

        current.setAbortAction(true);

        gs.addErrorMessage("Error, can't close the case.");

    }else {

        gs.addInfoMessage("Closed successfully");

    }

})(current, previous);

The updated multiple records data source: 

r

Thanks
