Hello, in Rhino 8 the plugin works fine on Windows, but on macOS, when the panel is closed and reopened, it becomes empty.
Is this something maybe related to macOS or etoforms?

using Rhino.PlugIns;using Rhino.UI;

namespace TestPlugin
{
  public class TestPlugin: PlugIn
  {
     public static TestPlugin Instance { get; private set; }  
     public TestPlugin ()
     {
        Instance = this;
     }

     protected override LoadReturnCode OnLoad(ref string errorMessage)
     {
        Panels.RegisterPanel(this, typeof(TestPanel), "Test", Properties.Resources.test);
        return LoadReturnCode.Success;
     }
  }
}

namespace TestRhino
{
    [Guid("EF3437E1-99A5-4408-A1F8-3721AA65525C")]
    public class TestPanel: Panel
    {
        public static Guid PanelId => new Guid("EF3437E1-99A5-4408-A1F8-3721AA65525C");

        private readonly PanelViewModel _viewModel;

        public TestPanel()
        {
            var geometryMap = ViewModelData.GetGeometryMap();
            var roofTypeMap = ViewModelData.GetRoofTypeMap();

            var uiManager = new UIManager(geometryMap, roofTypeMap);

            _viewModel = new PanelViewModel(uiManager, this);

            Content = uiManager.CreateLayout();

            _viewModel.HookEvents();
            _viewModel.InitializeState();
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing && Rhino.RhinoApp.IsClosing)
            {
                base.Dispose(disposing);
            }
        }
    }
}

Hello @seg,

On mac I used your code and tested it out.
macpan.zip (32.5 KB)

For me the panel opens and closes fine. Does this code work for you as well?

If you add a breakpoint after Content = uiManager.CreateLayout();
I’d be curious to see if Content is null or if IsDisposed is true or if Visible is false.

var geometryMap = ViewModelData.GetGeometryMap();
var roofTypeMap = ViewModelData.GetRoofTypeMap();

var uiManager = new UIManager(geometryMap, roofTypeMap);

_viewModel = new PanelViewModel(uiManager, this);

Content = uiManager.CreateLayout();

_viewModel.HookEvents();
_viewModel.InitializeState();
