Hi,
I'm trying to use a TableView as a viewer for my EMF data. I successfully managed to get this tutorial running and working: http://git.eclipse.org/c/efxclipse/org.eclipse.efxclipse.git/tree/demos/org.eclipse.fx.demo.contacts.app?h=2.4.0
Now, I have a problem when I try to reuse the ContactsTableView approach in my project:
public class MyTableViewController {
@FXML private TableColumn<TestObject, Boolean> colValid;
...
public void initTable(ModelService modelService) {
tableView.setItems(new AdapterFactoryObservableList<TestObject>(adapterFactory, modelService.getModel()));
...
colValid.setCellValueFactory(features -> BooleanProperty.booleanProperty(
EMFEditFXProperties.value(editingDomain, features.getValue(), MyTestPackage.eINSTANCE.getTestObject_Valid())); // <-------------------------- Exception
colValid.setCellFactory(CheckBoxTableCell.forTableColumn(colValid));
...
As stated in the above code an exception is being thrown:
...
Caused by: java.lang.NullPointerException

...
I guess the NPE is thrown, because the TestLevel class has no "valid" feature. But, I don't want to have TestLevel objects in my table - I only want TestObject objects in my table!!!
So, I guess there might be a problem with the AdapterFactoryObservableList and my model object, because it contains two containment references and all objects of both of these references are used as table items. My question is:
How can I control, that only those objects from the right containment reference are being used as items in the table?
Cheers,
Andreas
