Bug 132798 [Field Assist] - Pressing Backspace at offset 0 should not reload field assist popup
N20060322-0010. After migrating the Find/Replace dialog to the new field assist support I found the following blooper: pressing the Backspace key at offset 0 reloads the field assist popup. Test Case: 1. in a text editor press Ctrl+F 2. enable regex search 3. in the Find filed press Ctrl+Space 4. continuously press Backspace ==> each time the proposal list is reloaded.

popupSize = getShell().getSize();
			}
			getShell().setBounds(initialX, initialY, popupSize.x, popupSize.y);
			
			getShell().addListener(SWT.Resize, new Listener() {
				public void handleEvent(Event e) {
					popupSize = getShell().getSize();
					if (infoPopup != null) {
						infoPopup.adjustBounds();
					}
				}
			});

			TableItem item = (TableItem) event.item;
			int index = proposalTable.indexOf(item);

				item.setText(getString(current));
				item.setImage(getImage(current));
				item.setData(current);
