The CORRECT way to redirect to a ListView from StandardSetController?

Question

From a List Button or Visualforce Page, I wanna redirect to a ListView after. Common, right?

Life is great when we're dealing with Standard Controller: using view() method.

What is the correct, documented, future-proof way to do this from a Standard Set Controller?

public PageReference back() {

    //this seems so fragile and lightning-unfriendly: "/001?fcf=00B24000004cfLK"

    SelectOption listViewOption = controller.getListViewOptions()[0];

    PageReference pr = new PageReference('/' + SObjectType.Account.KeyPrefix);

    pr.getParameters().put('fcf', listViewOption.getValue().left(15));

    return pr;

}

I had some some ideas using ApexPages.Action but they caused kooky Internal Salesforce Errors:

public PageReference back() {

    String expression = '{!URLFOR($Action.My__c.List, $ObjectType.My__c)}';

    ApexPages.Action action = new ApexPages.Action(expression);

    return action.invoke();

}

Answer 1

Whoa. This works:

public PageReference listView() {

    return new ApexPages.Action('{!List}').invoke();
    //System.PageReference[/a09?fcf=00B24000004cfLK]

}

But is it documented?
