I make a window with a button, popup menu, and a text field. The button reads the popup menu selected row index and puts it in the text field.
Now, add a tab panel with a container control and put the text field and popup menu in the container. I get a reference to the container and otherwise run the same code. Now everything returns a nil object error
There was apparently a similar problem with list boxes a few years ago. Is there something I can do to get past this?
