JavaFX Row Not Updating - javafx

Question

There is a very similar question to this already, but mine's a bit different. I am using properties and on observable list to change it, it won't update.
Original question is here.
So when I am transferring rows between tables, like this:
The first row would appear, but when adding more than one would cause the ones after the first row to not update, like this:
They only reappear when I move around the columns though.
//Loot identification
TableColumn lootIdentCol = new TableColumn<>("Identification");
TableColumn<ItemDef, Integer> lootIDCol = new TableColumn<>("ID");
lootIDCol.setCellValueFactory(
new PropertyValueFactory<ItemDef, Integer>("id"));
TableColumn<ItemDef, String> lootNameCol = new TableColumn<>("Name");
lootNameCol.setCellValueFactory(
new PropertyValueFactory<ItemDef, String>("name"));
lootIdentCol.getColumns().addAll(lootNameCol, lootIDCol);
//Loot price
TableColumn<ItemDef, Integer> lootPriceCol = new TableColumn<>("Price");
lootPriceCol.setCellValueFactory(
new PropertyValueFactory<ItemDef, Integer>("price"));
//To loot items table
toLootItemsTableView.getColumns().addAll(lootIdentCol, lootPriceCol);
grid.add(toLootItemsTableView, 0, 1);
//Lootable items table
lootableItemsTableView.getColumns().addAll(lootIdentCol, lootPriceCol);
grid.add(lootableItemsTableView, 2, 1);
toLootItemsTableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
lootableItemsTableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
lootableItemsTableView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
toLootItemsTableView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
lootableTableList.add(new ItemDef("Ab", 141, false, false));
lootableTableList.add(new ItemDef("Ac", 25, false, false));
lootableTableList.add(new ItemDef("AD", 262, false, false));
AddRemoveButtons<ItemDef> addRemoveLootButtons = new AddRemoveButtons<>(
lootableTableList, lootableItemsTableView.getSelectionModel(),
toLootTableList, toLootItemsTableView.getSelectionModel()
);
Code for AddRemoveButtons:
private final ObservableList<E> fromList;
private final ObservableList<E> toList;
public AddRemoveButtons(final ObservableList<E> fromList, final SelectionModel<E> from,
final ObservableList<E> toList, final SelectionModel<E> to) {
this.fromList = fromList;
this.toList = toList;
setAlignment(Pos.CENTER);
setPadding(new Insets(5, 5, 5, 5));
setSpacing(15);
ObservableList<Node> children = getChildren();
Button moveInto = new Button("Add");
moveInto.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
if (from instanceof MultipleSelectionModel) {
MultipleSelectionModel<E> multipleFrom = (MultipleSelectionModel<E>) from;
ObservableList<Integer> selectedIndices = multipleFrom.getSelectedIndices();
for (int i : selectedIndices)
transfer(i, true);
} else
transfer(from.getSelectedIndex(), true);
}
});
Button delete = new Button("Del");
delete.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
if (to instanceof MultipleSelectionModel) {
MultipleSelectionModel<E> multipleFrom = (MultipleSelectionModel<E>) to;
ObservableList<Integer> selectedIndices = multipleFrom.getSelectedIndices();
for (int i : selectedIndices)
transfer(i, false);
} else
transfer(to.getSelectedIndex(), false);
}
});
children.addAll(moveInto, delete);
}
private void transfer(int index, boolean forward) {
if (forward)
toList.add(fromList.remove(index));
else
fromList.add(toList.remove(index));
}
ItemDef which implements Identifiable, Serializable, Comparable:
private final String name;
private final int id;
private final boolean members;
private final boolean stackable;
private int price;
public ItemDef(JSONObject jsonObject) {
this(
(String) jsonObject.get("name"),
Integer.parseInt((String) jsonObject.get("id")),
Boolean.parseBoolean((String) jsonObject.get("members")),
Boolean.parseBoolean((String) jsonObject.get("stackable"))
);
}
public ItemDef(String name, int id, boolean members, boolean stackable) {
this.name = name;
this.id = id;
this.members = members;
this.stackable = stackable;
price = -1;
}
public String getName() {
return name;
}
#Override
public int getId() {
return id;
}
public boolean isMembers() {
return members;
}
public boolean isStackable() {
return stackable;
}
public int getPrice() {
return price != -1 ? price : updatePrice();
}
//Other methods not relevant

Answer 1

Figured out why it kept doing that.
You just can't have the same TableColumn being referenced on multiple tables.

Answer 2

You should not share columns in multiple tables if you want data to update in multiple tables share the data set between them not the columns.
