title: VCL Register Properties in Category not working
body: <p>I am trying to group some properties of my component.</p>
  
  <pre><code>type
    TcxGridButton = class(TcxButton)
    private
      FGridView : TcxGridDBTableView;
      FPopup : TPopupMenu;
      FImages : TcxImageList;
      FSortFilterEnabled : boolean;
      FCustomizeAndGroupEnabled : boolean;
  
      procedure AutoSize(Sender : TObject);
      procedure ClearFilter(Sender : TObject);
      procedure ExportToExcel(Sender : TObject);
  
      procedure SortFilter(Sender : TObject);
      procedure CustomizeAndGroup(Sender : TObject);
  
      procedure OnPopup(Sender : TObject);
    protected
      { Protected declarations }
    public
      { Public declarations }
      constructor Create(AOwner : TComponent); override;
  
      procedure Click; override;
    published
      property GridView : TcxGridDBTableView read FGridView write FGridView;
      property AllowSortFilter : boolean read FSortFilterEnabled write FSortFilterEnabled;
      property AllowCustomizeAndGroup : boolean read FCustomizeAndGroupEnabled write FCustomizeAndGroupEnabled;
    end;
  </code></pre>
  
  <p>I wish to show AllowSortFilter and AllowCustomizeAndGroup in VCL under a Group named PopupMenu Settings.</p>
  
  <p>So I did this :</p>
  
  <pre><code>procedure Register;
  begin
    RegisterComponents('Roberts', [TcxGridButton]);
  
    RegisterPropertiesInCategory('PopupMenu Settings', TcxGridButton, ['AllowSortFilter','AllowCustomizeAndGroup']);
  end;
  </code></pre>
  
  <p>Unfortunately this is not working, and I have no idea why. The Syntax seems to be correct get no errors . But the Group is not being created.</p>
  
  <p>Regards
  Robert</p>
