Error when using dynamic picklist of collaborationGroup as design attribute in lightning app builder

1) In a org create a chatter group
2) Create the following Apex Class
global class GroupPicklist extends VisualEditor.DynamicPickList{

list<CollaborationGroup> groupList = new list<CollaborationGroup>([Select Id,Name FROM CollaborationGroup WHERE IsArchived = FALSE]);

global override VisualEditor.DataRow getDefaultValue(){
VisualEditor.DataRow defaultValue = new VisualEditor.DataRow('Select One','SELECTONE');
IF(grouplist.size() > 0){
string groupName = groupList[0].Name;
string groupId = groupList[0].Id;
VisualEditor.DataRow populatedValue = new VisualEditor.DataRow(groupName,groupId);
return populatedValue;
return defaultValue;
global override VisualEditor.DynamicPickListRows getValues() {
VisualEditor.DynamicPickListRows myValues = new VisualEditor.DynamicPickListRows();
list<VisualEditor.DataRow> DataRowList = new list<VisualEditor.DataRow>();
FOR (CollaborationGroup cg : groupList){
string cgName = cg.Name;
string cgId = cg.Id;
VisualEditor.DataRow dr = new VisualEditor.DataRow(cgName,cgId);
return myValues;

3) Create the following lightning component:


<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes">
<aura:attribute name="groupId" default="select one" type="String" required="true" description="18 char id" />
<forceChatter:publisher context="RECORD" recordId="{!v.groupId}" />
<forceChatter:feed type="Record" subjectId="{!v.groupId}" feedDesign="DEFAULT"/>


<design:component >
<design:attribute name="groupId" default="Select Group" label="Select Group" datasource="apex://GroupPicklist" description="dynamic picklist" placeholder="select group" />

4) Add the component to a page, choose the group and click save

Actual behavior:
IDE gacks with: We had trouble processing the request. We've reported the problem to Customer Support with error ID: -1711986293

Expected behaviour:
IDE saves without any issue.


Is it Fixed?
