This is my JavaFX code and I am trying to create a to-do list. When I try to populate my Task tab, it is not accepting the entry. The rest of the tab is accepting the entries.
I believe it has to do with the setter and getter methods. I tried using the lambda expression instead of the PropertyValue() but could not find the solutions.
The text field is supposed to accept the entry when the user enters any input.
