JavaFX with fxml TableView updating some columns but not others

Question

In my application Some of the columns in my table are populating like they should be the columns labeled Name Priority and BurstTime have the correct values being added but for some reason the other two ProcessID and State do not update with the values I am adding to my ArrayList.

It looks like my code should be working can anybody see something I have missed?

Here is my controller

package application;

import java.net.URL;
import java.util.ResourceBundle;

Here is my class for Procsess

package application;


public class Process {

String processTypeP = "";
String priorityCodeP = "0";
int lineCodeP = 0;
String burstTimeP = "0";
String processIDP = "0";
String StatusCodeP = "0";

public Process (){} 

public String getProcessTypeP() {
    return processTypeP;
}
public void setProcessTypeP(String processTypeP) {
    this.processTypeP = processTypeP;
}

public String getPriorityCodeP() {
    return priorityCodeP;
}
public void setPriorityCodeP(String priorityCodeP) {
    this.priorityCodeP = priorityCodeP;
}

public int getLineCodeP() {
    return lineCodeP;
}
public void setLineCodeP(int lineCodeP) {
    this.lineCodeP = lineCodeP;
}

public String getBurstTimeP() {
    return burstTimeP;
}
public void setBurstTimeP(String burstTimeP) {
    this.burstTimeP = burstTimeP;
}

     public String getprocessIDP() {
    return processIDP;
}
public void setprocessIDP(String processIDP) {
    this.processIDP = processIDP;
}

    public String getstatusCodeP() {
    return StatusCodeP;
}
public void setstatusCodeP(String StatusCodeP) {
    this.StatusCodeP = StatusCodeP;
}



}

Here is my main application

package application;



import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;

import javafx.scene.Scene;


import javafx.scene.layout.AnchorPane;



public class Main extends Application {

@Override
public void start(Stage primaryStage) {
    try {
        FXMLLoader loader = new FXMLLoader(Main.class.getResource("/Main.fxml"));
    //  Parent root = FXMLLoader.load(getClass().getResource("/Main.fxml"));
        AnchorPane root = (AnchorPane) loader.load(Main.class.getResource("/application/Main.fxml"));
        Scene scene = new Scene(root);
        scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
        primaryStage.setScene(scene);
        primaryStage.show();
    } catch(Exception e) {
        e.printStackTrace();
    }


}

public static void main(String[] args) {
    launch(args);
}
}

Answer 1

Try renaming your getter methods from getprocessIDP and getstatusCodeP to getProcessIDP and getStatusCodeP respectively (note the capital 'S' and 'P'). To avoid problems like this in the future it's a good habit to generate getters, setters and constructors with the IDE instead of doing it manually.
