Still working through this, but you have got me further into JavaFx than anyone else so far. Many thanks.

Thank you so much for this and last video! Truly helped so much! God bless!

Hello! Congratulations! It's a great program. It's working! But I realize that there is a situation: if the caps lock is activated, the "ERROR: Paste NOT allowed" does not work. Instead, "ERROR: Max Number Input" appears if you paste a string longer than 6 characters. How can we fix this?

Hello, thanks for your explanations, I email you but I don't receive any code ?

Thank you so much for this JavaFX tutorial.


I started well but I'm getting an error in the ValidateTextField.java file

final Boolean INVALID_KEY
= (!Character.isDigit(CTRL_V == currentKeyTyped)) // if not number remove key pressed and show error
&& (currentKeyTyped != BACK_SPACE)//but allow this key
&& (currentKeyTyped != DEL)//allow this key
&& (currentKeyTyped != ENTER) // allow this key
&&

on the second line


and here too

return new ErrorMessage(error, errorMsg);// return object ErrorMessage

}catch(Exception ex){

return new ErrorMessage(true, "ERROR: Exception Caught ");
}
