JavaFX Tableview not populating data to column - javafx

Question

I am trying to create a TableView with 1 counter + 4 value columns. But for some unknown reason, columns val3, val4 are not getting populated in the tableview. I have updated the getVal2() method with "val3.get()", and I could see the val3 value in column of Value2. So, I suspect that there is some problem with reading to column Value3. I have also checked the naming convention/camel-casing. It looks fine to me. Can any help me fix this ?
ObservableList<Counters> data = FXCollections.observableArrayList();
Iterator<String> counterIterator = counterMap.keySet().iterator();
while(counterIterator.hasNext()) {
String counter = counterIterator.next();
String[] values = counterMap.get(counter);
String val1 = "a", val2 = "b", val3 = "c", val4 = "";
Counters counters = new Counters(counter, val1, val2, val3, val4);
data.add(counters);
}
TableView<Counters> table = new TableView<Counters>();
table.setEditable(true);
TableColumn<Counters, String> counter = new TableColumn<Counters, String>("Counter");
counter.setCellValueFactory(new PropertyValueFactory<Counters, String>("counter"));
TableColumn<Counters, String> val1 = new TableColumn<Counters, String>("Value1");
val1.setCellValueFactory(new PropertyValueFactory<Counters, String>("val1"));
TableColumn<Counters, String> val2 = new TableColumn<Counters, String>("Value2");
val2.setCellValueFactory(new PropertyValueFactory<Counters, String>("val2"));
TableColumn<Counters, String> val3 = new TableColumn<Counters, String>("Value3");
val3.setCellValueFactory(new PropertyValueFactory<Counters, String>("val3"));
TableColumn<Counters, String> val4 = new TableColumn<Counters, String>("Value4");
val3.setCellValueFactory(new PropertyValueFactory<Counters, String>("val4"));
table.getColumns().add(counter);
table.getColumns().add( val1);
table.getColumns().add( val2);
table.getColumns().add( val3);
table.getColumns().add( val4);
table.setItems(data);
public static class Counters {
private SimpleStringProperty counter, val1, val2, val3, val4;
public Counters(String counter, String val1, String val2, String val3, String val4) {
this.counter = new SimpleStringProperty(counter);
this.val1 = new SimpleStringProperty(val1);
this.val2 = new SimpleStringProperty(val2);
this.val3 = new SimpleStringProperty(val3);
this.val4 = new SimpleStringProperty(val4);
}
public String getCounter() {
return counter.get();
}
public void setCounter(String counter) {
this.counter.set(counter);
}
public String getVal1() {
return val1.get();
}
public void setVal1(String val1) {
this.val1.set(val1);
}
public String getVal2() {
return val2.get();
}
public void setVal2(String val2) {
this.val2.set(val2);
}
public String getVal3() {
return val3.get();
}
public void setVal3(String val3) {
this.val3.set(val3);
}
public String getVal4() {
return val4.get();
}
public void setVal4(String val4) {
this.val4.set(val4);
}
}

You have a copy-paste typo in
TableColumn<Counters, String> val4 = new TableColumn<Counters, String>("Value4");
val3.setCellValueFactory(new PropertyValueFactory<Counters, String>("val4"));
Should be
TableColumn<Counters, String> val4 = new TableColumn<Counters, String>("Value4");
val4.setCellValueFactory(new PropertyValueFactory<Counters, String>("val4"));
and val4 is always val4 = "" thats why it looks like they both are empty
