当通过单击列标题对TableView进行排序时,复选框行为将变为意外。如果您检查其中一个,则另一个似乎与它绑定,并且也会被选中。
在对TableView进行排序之前,一切都按预期工作,但是一旦触发排序,行为就会出乎意料。
我正在使用CheckBoxTableCell
,在Windows 8 64位上运行JDK 1.8.0-ea-b106
64位。
这是一个SSCCE:

table.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
TableColumn<Person, String> colFirstName = new TableColumn<>("First Name");
colFirstName.setCellValueFactory(p -> p.getValue().firstName);
colFirstName.setCellFactory(TextFieldTableCell.forTableColumn());
colFirstName.setOnEditCommit(event -> event.getTableView().getItems().get(event.getTablePosition().getRow()).firstName.set(event.getNewValue()));
TableColumn<Person, String> colLastName = new TableColumn<>("Last Name");

colInvited.setCellFactory(CheckBoxTableCell.forTableColumn(colInvited));
table.getColumns().addAll(colFirstName, colLastName, colInvited);
stage.setScene(new Scene(new StackPane(table)));
stage.setTitle("CheckBoxTableCell Bug");
stage.show();
}
class Person {
public StringProperty firstName;
public StringProperty lastName;
public BooleanProperty invited;
public Person() {
this.firstName = new SimpleStringProperty("");
this.lastName = new SimpleStringProperty("");
this.invited = new SimpleBooleanProperty(false);
}
public Person(String fname, String lname, boolean invited) {
this();
this.firstName.set(fname);
this.lastName.set(lname);
this.invited.set(invited);
}
}
}
如何重现错误:
正如预期的那样,该错误也存在于Ensemble(JavaFX示例附带的应用程序)中。
任何想法如何解决这个问题?
