This is the story - I’ve created a class object (Class1). I’ve dragged and dropped Class1 to Menu Items\Action, so object was created (Class1_menuItem). Now, I dragged and dropped Class1_menuItem to Form1\ActionPane\ButtonGroup, and object was created.
Now, the problem. I renamed Class1 into Class1a, and when I try to open Form1, client crashes. So, I created new class, new menu item, and tried to drag and drop new menu item to Form1\ActionPane\ButtonGroup, but I can’t drop the menu item object there.
You should have updated the menu item after renaming your class.
Now please explain why you can’t drop a menu item there. What happens? Also note that you can add a new menu item button and link it to your menu item.
Apparently there’s an occasional issue in the project tree nodes (suggested to me by other dev) with dragging object from project tree node to destination object in the same project tree node. When I dragged from one AOT to other AOT, it worked flawlessly.
That was just the part of my problem. The main problem was that when I click on that menu item in Workspace, my Client crashes.
