TLMDPropertyInspector hides properties if more than one component is added

  I cannot reproduce this issue. Everything works fine:

  
  

  type

    TFoo = class(TPersistent)

    private

      FS: string;

    published
  

      property S: string read FS write SetS;

    end;

  
  

  procedure TForm1.Button1Click(Sender: TObject);
  

  begin

    LMDSimplePropInspector1.Objects.Add(TFoo.Create);

    LMDSimplePropInspector1.Objects.Add(TFoo.Create);

  end;

  Generally, this is controlled by the praMultiSelect attribute of the property editor. So, some specific properties, which have specialized property editors can be hidden when several objects are added. One example of such kind of properties is TComponent.Name.

  I have a property of a self defined type of string:

  
  

  TMyString = type string;
  

  
  

  Type

    TMyObject = class (TPersistent)

      private

        FS: TMyString;

      published

        property S: TMyString read FS write FS;

    end;

  Strange. It should work. I've checked this case (TMyString = type string) also before answering you last time.

  Can you then create a small demo project and send it to our support email?

  Okay, trying to build a demo project I recognized that I registered an own property editor for "TMyString". It seems that this is the reason why TMyString property is not shown if I select more than one objects.

  The solution is to use praMultiSelect attribute:

  
  

  function TMyStringPropEditor.GetAttrs: TLMDPropAttrs;

  begin

    Result := [praDialog, praMultiSelect];

  end;

  This works!

  Thank you for helping me!
