Question

Hey all I am not able to get the following code to work. it keeps giving me this error when I click on the textfield:

Aug 15, 2024 10:41:01 PM javafx.scene.CssStyleHelper calculateValue
WARNING: Caught 'java.lang.ClassCastException: class java.lang.String cannot be cast to class javafx.scene.paint.Paint (java.lang.String is in module java.base of loader 'bootstrap'; javafx.scene.paint.Paint is in module [email protected] of loader 'app')' while converting value for '-fx-border-color' from rule '*.text-input:focused' in stylesheet file:/C:/Users/Me/eclipse-workspace2/testMatBtn/bin/application/extended.css

I’m not really sure where its saying its having the issue at in my java controller:

I normally do not post my full code but decided to do so this time since I’m told a lot to add more code for the issue.

Anyone know why it’s giving me those errors?
