DynamicPickList Class getDefaultValue() method not working

Hi!, 

I'm populating a configuration picklist using DynamicPickList class in lightning component app builder page, but it seems that getDefaultValue() method is not working. I even copied/pasted Salesforce example and it didn`t work either! :(

This is salesforce example: (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_class_VisualEditor_DynamicPickList.htm#apex_class_VisualEditor_DynamicPickList) 
global class MyCustomPickList extends VisualEditor.DynamicPickList{
    
    global override VisualEditor.DataRow getDefaultValue(){
        VisualEditor.DataRow defaultValue = new VisualEditor.DataRow('red', 'RED');
        return defaultValue;
    }
    global override VisualEditor.DynamicPickListRows getValues() {
        VisualEditor.DataRow value1 = new VisualEditor.DataRow('red', 'RED');
        VisualEditor.DataRow value2 = new VisualEditor.DataRow('yellow', 'YELLOW');
        VisualEditor.DynamicPickListRows  myValues = new VisualEditor.DynamicPickListRows();
        myValues.addRow(value1);
        myValues.addRow(value2);
        return myValues;
    }
}

And this is the picklist output in lightning app builder:

Anyone is having the same issue? Is something that I missed here?

Thanks!

Hello,

The best article about the dynamic picklist (complete use, better than the Salesforce documentation):

https://agarciaodeian.com/2017/08/08/picklist-dinamicos-en-lightning-components/

The VisualEditor.DataRow seems just useful for selecting the default values.

Gonzalo Quevedo 15,

I'm glad you reported this issue as we are experiencing the exact same behavior you are. Within the Lightning App Builder, after initially dragging-and-dropping our Lightning component onto the page, the initial default value of our drop down is an empty value:

Empty Default Value

Here is my code:

Lightning design file: 
<design:component label="Conga Composer">
    <design:attribute name="selectedCollectionId" label="Solution Collection" description="This will determine which solutions are displayed" datasource="apex://SolutionCollectionDesigner" required="false" />
</design:component>

Apex class: 
public with sharing class SolutionCollectionDesigner extends VisualEditor.DynamicPickList {
    
    public override VisualEditor.DataRow getDefaultValue() {
        System.debug('TEST getDefaultValue()'); //TODO
        VisualEditor.DataRow defaultValue;
        ESAPI.accessController().setSharingMode(SFDCAccessController.SharingMode.WITH);
        if(ESAPI.accessController().isAuthorizedToView(Conga_Collection__c.sObjectType, new List<String>{'Id', 'Name'})) {
            for (Conga_Collection__c c : [SELECT Id, Name FROM Conga_Collection__c ORDER BY Name ASC LIMIT 1]) {
                defaultValue = new VisualEditor.DataRow(c.Name, String.valueOf(c.Id), true);
            }
        }

        return defaultValue;
    }
    
    public override VisualEditor.DynamicPickListRows getValues() {
        System.debug('TEST getValues()'); //TODO
        VisualEditor.DynamicPickListRows  myValues = new VisualEditor.DynamicPickListRows();
        Integer index = 0;
        Boolean selected = false;
        ESAPI.accessController().setSharingMode(SFDCAccessController.SharingMode.WITH);
        if(ESAPI.accessController().isAuthorizedToView(Conga_Collection__c.sObjectType, new List<String>{'Id', 'Name'})) {
            for (Conga_Collection__c c : [SELECT Id, Name FROM Conga_Collection__c ORDER BY Name ASC]) {
                selected = (index++ == 0) ? true : false;
                VisualEditor.DataRow tempVal = new VisualEditor.DataRow(c.Name, String.valueOf(c.Id), selected);
                myValues.addRow(tempVal);
            }
        }

        return myValues;
    }

}

Suspected Salesforfce Bug:
The Salesforce provided Apex method fails to invoke (my system.debug() statement fails to execute): 
public override VisualEditor.DataRow getDefaultValue() {
        System.debug('TEST getDefaultValue()'); //TODO
        VisualEditor.DataRow defaultValue;
        ESAPI.accessController().setSharingMode(SFDCAccessController.SharingMode.WITH);
        if(ESAPI.accessController().isAuthorizedToView(Conga_Collection__c.sObjectType, new List<String>{'Id', 'Name'})) {
            for (Conga_Collection__c c : [SELECT Id, Name FROM Conga_Collection__c ORDER BY Name ASC LIMIT 1]) {
                defaultValue = new VisualEditor.DataRow(c.Name, String.valueOf(c.Id), true);
            }
        }

        return defaultValue;
    }
