Description Mark Gaylard

I'm having trouble getting a dialog to open with the initial selection shown. 
I've stepped through the code and everything seems to be fine until I 
hit FilteredList$TableUpdater.run(). In here, it resets the table 
selection to item 0 (FilteredList.java line 509). This happens after the 
showSelection() method in Table.class. 

The order I'm creating/setting things is:

dialog = new ElementListSelectionDialog(...)
dialog.setIgnoreCase(false)
dialog.setMultipleSelection(true)
dialog.setElements(...)
dialog.setInitialSelection(...)
dialog.open()


The elements in the initialSelection list are in the elements list 
(FilteredList.setSelection(Object[] elements) finds and matches them ok). 

When the dialog is shown, the first element is selected, but only as a 
"non-focused control" selection.

Moving to Lynne as she is looking at this dialog right now.

Please give me an example demonstrating your problem.  I am running the current 
2.1 build.  If I run the following, the items are selected and focus is in the 
text field (as expected).

import org.eclipse.jface.viewers.ILabelProvider;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.dialogs.ElementListSelectionDialog;

public class TestElementSelectionDialog {
    public static void main (String [] args) {
        Display display = new Display ();
        Shell shell = new Shell (display);
        ILabelProvider labelProvider = new LabelProvider();
        ElementListSelectionDialog dialog = new ElementListSelectionDialog
(shell, labelProvider);
        dialog.setIgnoreCase(false);
        dialog.setMultipleSelection(true);
        dialog.setElements(new String[] 
{"a123", "a456", "b789", "a111", "a222"});
        dialog.setInitialSelections(new String[] {"a123", "a456", "a111"});
        dialog.setFilter("a");
        dialog.open();
    }
}
