_tkinter.TclError: bad listbox index "": must be active, anchor, end, @x,y, or a number with entry.select_adjust(END)

Question

I have a problem with entry.select_adjust(). The code is like below.

The error is occurred at self.rename_entry_mpf.select_adjust(END). If I delete this line, the program works properly. But I want to highlight the file name when I click the file to rename. That's why I used select_adjust. With "select_adjust", when I click the file, the entry is created and the name of file is displayed and highlighted. Then I write anything, even though I pushed just return button, the error is occured.

I edited my post and almost code is like below.

Even I wrote any name but it is entered "". How can I solve this problem?
