Bug 300979

Build id: I20100126-0800

Combo.setListVisible(true) doesn't show the drop-down list. 
For READ_ONLY combo it changes the selection, but after the call to setListVisible() the Combo list items can't be selected.

testcase:

public class Snippet  {
public static void main(String[] args) {
	Display display = new Display();
	Shell shell = new Shell(display);
	shell.setLayout(new GridLayout());
	final Combo combo = new Combo(shell, SWT.READ_ONLY);
	combo.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
	combo.setText("Here is some text");
	combo.add("abc");
	combo.add("efg");
	combo.add("iii");
	Button button = new Button(shell, SWT.PUSH);
	button.setText("show");
	button.addSelectionListener(new SelectionAdapter() {
		public void widgetSelected(SelectionEvent e) {
			combo.setListVisible(true);
		}
	});
	shell.pack();
	shell.open();
	while (!shell.isDisposed()) {
		if (!display.readAndDispatch())
			display.sleep();
	}
	display.dispose();
}
}
