Lightning: Get list view records

Question

How can one get ALL the records from a list view in a visualforce page running in Lightning? (Since no checkbox for selecting are available)

Similar old question.

With an adaptation from that question's answer, I have:

public SomeClass(ApexPages.StandardSetController con) {
    if (con.getSelected().size() > 0)
        lots = [SELECT Name FROM Custom__c WHERE Id IN :con.getSelected()];
    else {
        Transient Set<sObject> sObjects = new Set<sObject>();
        sObjects.addAll(con.getRecords());
        while (con.getHasNext()) {
            con.next();
            sObjects.addAll(con.getRecords());
        }
        lots = [SELECT Name FROM Custom__c WHERE Id IN :sObjects];
    }
}

And this works fine in Salesforce Classic, for each condition. But in lightning it works differently each time, looks like every time I test this, it chooses a different list to get the records. (Looks like a SF bug)

Answer 1

Bit of a shot in the dark, but try calling setFilterId on your StandardSetController to get more deterministic behavior.

public static final String DESIRED_LISTVIEW_LABEL = 'All';
public SomeClass(ApexPages.StandardSetController controller)
{
    if (!controller.getSelected().isEmpty())
        return [SELECT Name FROM MyObject__c WHERE Id IN :controller.getSelected()];
    for (SelectOption listViewOption : controller.getListViewOptions())
    {
        if (listViewOption.getLabel() == DESIRED_LISTVIEW_LABEL)
        {
            controller.setFilterId(listViewOption.getValue());
            break;
        }
    }
    // do stuff
}

You can also expose the available filters ( List<SelectOption>) returned from getListViewOptions() as a property on your controller and let the end user decide which list view they want.

Update Lightning does not support Javascript buttons.

You do not need to add an extra user input step. Instead of making DESIRED_LISTVIEW_LABEL final, you can get it through page parameters if you make your list button Execute Javascript as follows:

(function (w) {
    "use strict"
    var fcf, index, payload, search = window.location.search,
        params = search.substring(1, search.length).split('&');
    for (i in params) {
        payload = params[i].split('=');
        if (payload[0] == 'fcf') {
            fcf = payload[1];
            break;
        }
    }
    w.open('/apex/MyPage?ListView=' + fcf);
})(window);

You could simplify the above somewhat since fcf seems to be the only parameter most of the time, but I tried to make it robust against future changes in the url. Then you can do:

public static final String LISTVIEW_PARAM = 'ListView';
public Id desiredFilterId
{
    get
    {
        return ApexPages.currentPage().getParameters().get(LISTVIEW_PARAM);
    }
}
public SomeClass(ApexPages.StandardSetController controller)
{
    if (!controller.getSelected().isEmpty())
        return [SELECT Name FROM MyObject__c WHERE Id IN :controller.getSelected()];
    if (String.isNotBlank(desiredFilterId))
        controller.setFilterId(desiredFilterId);
    // do stuff
}
