I have been trying to recreate an example of a database editor in 7.9.10 by following the instruction from the following link.
The issue I’m having is that i get an error when I go to test the first part of the example by clicking the add button. Here is the following error I get:
Traceback (most recent call last):
File “event:actionPerformed”, line 3, in
AttributeError: ‘NoneType’ object has no attribute ‘text’
I have followed the example step by step. Thinking it might be an issue with copying and pasting the script.
