Answer 1

welcome to Stack Overflow!

The important line in your error message is this one:

Caused by: javafx.fxml.LoadException: Error resolving onEditStart='#click', either the event handler is not in the Namespace or there is an error in the script.
/D:/work%20proyeqt%20immidetely/WorkWithTable/out/production/WorkWithTable/sample/sample.fxml:15

This means that there is an error on line 15 of sample.fxml, specifically where it says onEditStart='#click' . Either it can't resolve 'onEditStart' or click() isn't a function in the controller.

Answer 2

Caused by: javafx.fxml.LoadException: Error resolving onEditStart='#click', either the event handler is not in the Namespace or there is an error in the script.
/D:/work%20proyeqt%20immidetely/WorkWithTable/out/production/WorkWithTable/sample/sample.fxml:15

Probably you have click method on your button but you don't have it in your controller class
