**My Goal**
-----------

I have an editable table with a boolean column where one can check or uncheck the containing checkboxes and a multiple row selection policy. I would like my table to automatically toggle all checkboxes of all selected rows as soon as i check or uncheck one.
Don't know if you get the point :D I mean:

1. I select multiple rows
2. I check or uncheck the checkbox of one of those selected rows
3. All other rows's checkboxes get automatically checked or unchecked

Now it should be clear ;)

**My Question**
---------------

(I'm new to JavaFX! I've already done the same thing I'm asking for with AWT/SWING, but am not able to get it working with JavaFX)

Is there similar already built in JavaFX? If not, what is the best aproch to get to my goal?

**What I've done so far**
-------------------------

I've found out, that you can listen for a change event by setting a CheckBoxTableCell-Callback to the desired Column's CellFactory. I did it like so:

```
TableColumn<FileSelection, Boolean> selectedColumn = new TableColumn<>("Sel");
selectedColumn.setCellValueFactory(new PropertyValueFactory<>("selected"));
selectedColumn.setCellFactory(CheckBoxTableCell.forTableColumn(rowidx -> {
    if (tblVideoFiles.getSelectionModel().isSelected(rowidx)) {
        tblVideoFiles.getSelectionModel().getSelectedItems().forEach(item -> {
            if (!item.getFile().equals(tblVideoFiles.getItems().get(rowidx).getFile())) {
                item.selectedProperty().set(!item.selectedProperty().get());
             }
         });
     }
     return fileList.get(rowidx).selectedProperty();
}));

```

The problem here: As soon as a checkbox gets changed, it toggels itself, resulting in a toggle-loop of checking and unchecking itself :D
How can I stop this?
