Hello Everyone!
I use menubar in my B4J application. As it works for several companies, the menu structure/language may vary. I have created some subs to load the menu from file. The file contains the same text as it is in the menu designer. The subs are in the main. I thought I would move these subs to a class. The menu loads the same way, but does not respond to clicks. What do I need to do to get it right?
Here is the working code. If I move this code to a class, it will work, except the click event.
thanks in advance
Steven

Calling code:
    loadMenu("MenuBar1",MenuBar1,"menu.json")
Here is the whole code:
#region program menü betöltése fájlból

            parser.Initialize(File.ReadString(File.DirApp,fname))
            Dim jroot As List = parser.NextArray
            For Each mp As Menu In main_menubar.Menus
