I have a javafx project that is supposed to grab information through tcp pings from a server and constantly update a label. I used the JFX class Scheduled Service to implement this feature, and I tested by having it increment a number every 5 seconds, and that worked 100% as it should. However when I tried the same thing with a tcp ping to fetch information from the server, the server does recognize the message and responds but my label just goes blank. Here is the method in my jfx controller class
{ swissservice sak = new swissservice( "getquestion", gameidtext.getText(), placeholder, placeholder,3335);
sak.setExecutor(ThreadPoolExecutor1);
sak.setPeriod(Duration.seconds(1));
cardfinal.textProperty().bind(sak.valueProperty());}
I've tried using both bind and settext (only settext() worked on my original test for the incrementing ), I've also tried changing up what it binds/settext's to by changing it to getvalue/messageproperty and a couple of others.
Here is the code needed for the MRE
