Begin
    Mb := MetabaseClass.Active;
    Type := MetabaseSpecialObject.CustomExtender;
    Target := WinApplication.Instance.GetPluginTarget("Std");
    Context := Target.CreateExecutionContext;
    Data := New Variant[2];
    CustomExtender := Mb.SpecialObject(Type).Bind As IMetabaseCustomExtender;
    Data[0] := MetabaseClass.Active;
    Data[1] := CustomExtender.Classes.FindById("CUSTOMCLASS").Key;
    Context.Data := Data;
