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.

if ((triggerKeyStroke.getModifierKeys() == KeyStroke.NO_KEY && triggerKeyStroke
								.getNaturalKey() == e.character)

								(triggerKeyStroke.getNaturalKey() == e.keyCode && ((triggerKeyStroke
										.getModifierKeys() & e.stateMask) == triggerKeyStroke
										.getModifierKeys()))) {
							
							
							e.doit = false;
							openProposalPopup();
							return;
						}
					}
