ElementListSelectionDialog has no elements

Question

I am trying to use ElementListSelectionDialog . I followed the code example, but for some reason the dialog is shown, but without parameters

My code is:

ElementListSelectionDialog dialog = new ElementListSelectionDialog(shlSpriteCreator, new LabelProvider()); dialog.setMultipleSelection(false); dialog.setIgnoreCase(true); dialog.setAllowDuplicates(true); dialog.setMessage("Select an AI"); dialog.setTitle("What AI to use?"); dialog.setElements(new String[]{"HELLO","GOODBYE"}); if (dialog.open() == Window.OK) { aiControllerLocation = (String) dialog.getFirstResult(); } 

As a result of the dialogue:

I originally used an array of classes, but since it did not work, I replaced the list of trivial strings, although, as far as I understand, using a LabelProvider class should be able to use any object, and it will be displayed by it in the toString () view.

This type of dialog usually works under the Workbench interface. To run this dialog correctly, you must use the sample code.

 ElementListSelectionDialog dialog = new ElementListSelectionDialog(PlatformUI.getWorkbench().getDisplay().getActiveShell(), new LabelProvider());
