When i try to get password value from JfxpasswordField i get the exception bellow. After doing Research i came across a solution which suggested i use scene bulder 8.5 but unfortunately that didn't solve my problem. Kindly assists in resolving this issue
below is the code caption producing the error .The error is occuring in this line
PasswordValue = password.getText();
here is the code snippet
package com.kayseensystems.posmaxpro;
import com.jfoenix.controls.JFXTextField;

PasswordValue = password.getText();
System.out.println("Username="+usernamevalue+" "+PasswordValue);
try {

notify.showError();
}else{

.title("Login").text("Logged in Successful")
.graphic(null).hideAfter(Duration.seconds(5))

notify.showInformation();
}
} catch (Exception e) {
e.getCause().printStackTrace();
}
