From Jim Weaver's Learn JavaFX Weblog
As I mentioned in my post a week ago, this JavaFX Puzzler will require writing a compiled JavaFX Script program. In subsequent posts on my Learning JavaFX weblog, I've provided instructions for using the OpenJFX Compiler to compile a JavaFX Script program into Java bytecode, and to run the program. If you haven't seen these posts, please review them first.
The first person to post a comment with a correct solution will be given a free JavaFX Script: Dynamic Java Scripting for Rich Internet/Client-side Applications eBook (PDF download). When submitting your answer, be sure to put your correct email address in the "Email Address: (Not displayed with comment.)" text field on the comment form so that I can contact you with the information to obtain your free eBook. 
Requirements for Puzzler 4: The Puzzler4Compiled Program
Here is the console output of the sample solution:
changingText was replaced with Hello
The requirements for this program are as follows:
- The console output must be the same as shown above
- The program must define a class named Puzzler4Compiled that has an attribute named changingText that is of type String.
- The changingText attribute must have an on replace trigger that prints "changingText was replaced with" followed by the new value of the changingText attribute.
- An instance of the Puzzler4Compiled class must be created, setting the value of the changingText attribute to "Hello". This causes the trigger to be executed, and the output shown above to be printed on the console.
Have fun with this JavaFX Puzzler!
