J-Link, UIShowMessageDialog, MessageDialogOptions. Simple code does not work.

Hello all!

Trying to change the name of the dialog box. To display the window I use the UIShowMessageDialog method. If its second parameter is null, then the window name is "Info". I use MessageDialogOptions.SetDialogLabel to set my value. Implemented the interface, and its void method is SetDialogLabel.

The IDE throws the following error:

The method UIShowMessageDialog (String, MessageDialogOptions) in the type Session is not applicable for the arguments (String, void).

My code:

import com.ptc.cipjava.jxthrowable;
import com.ptc.pfc.pfcSession.Session;
import com.ptc.pfc.pfcSession.CreoCompatibility;
import com.ptc.pfc.pfcSession.pfcSession;
import com.ptc.pfc.pfcUI.MessageButton;
import com.ptc.pfc.pfcUI.MessageButtons;
import com.ptc.pfc.pfcUI.MessageDialogOptions;
import com.ptc.pfc.pfcUI.MessageDialogType;

public class TestApp {

      public static void start() throws jxthrowable{

          Session curSession = pfcSession.GetCurrentSessionWithCompatibility(CreoCompatibility.C4Compatible);
          MessageDialogOptions h = new SetDL();
          curSession.UIShowMessageDialog("Hello!", h.SetDialogLabel("my title"));
      }

      public static void stop() throws jxthrowable{
          Session curSession = pfcSession.GetCurrentSessionWithCompatibility(CreoCompatibility.C4Compatible);
          curSession.UIShowMessageDialog("Goodbye!", null);
      }

class SetDL implements MessageDialogOptions{

      @Override
      public void xdelete() throws jxthrowable {
      // TODO Auto-generated method stub
      }

      @Override
      public long getptr() {
      // TODO Auto-generated method stub
      return 0;
      }

      @Override
      public MessageButtons GetButtons() throws jxthrowable {
      // TODO Auto-generated method stub
      return null;
      }

      @Override
      public MessageButton GetDefaultButton() throws jxthrowable {
      // TODO Auto-generated method stub
      return null;
      }

      @Override
      public MessageDialogType GetMessageDialogType() throws jxthrowable {
      // TODO Auto-generated method stub
      return null;
      }

      @Override
      public void SetButtons(MessageButtons arg0) throws jxthrowable {
      // TODO Auto-generated method stub
      }

      @Override
      public void SetDefaultButton(MessageButton arg0) throws jxthrowable {
      // TODO Auto-generated method stub
      }

      @Override
      public void SetDialogLabel(String arg0) throws jxthrowable {
      // TODO Auto-generated method stub
      System.out.println(arg0);
      }

      @Override
      public void SetMessageDialogType(MessageDialogType arg0) throws jxthrowable {
      // TODO Auto-generated method stub
      }

      @Override
      public String GetDialogLabel() throws jxthrowable {
      // TODO Auto-generated method stub
      return null;
      }

}

Help me please to solve this problem.

Best Regards!
