Bug 178297 [Dialogs] - remove required field color
There are still some dialogs using the (now deprecated) class FieldAssistColors. We shouldn't color the required fields anymore in these dialogs: NewFolderDialog CreateLinkedResourceGroup ResourceWorkingSetPage ContainerSelectionGroup ResourceAndContainerGroup
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/ide/dialogs/CreateLinkedResourceGroup.java
String lastSegment = linkTargetPath.lastSegment();
						if (lastSegment != null) {
							lastUpdatedValue = lastSegment;
							updatableResourceName.setValue(lastSegment);
						}
					}
				}
				if (listener != null) {
					listener.handleEvent(new Event());
				}
			}
		});
		
		browseButton = new Button(linkTargetGroup, SWT.PUSH);
		browseButton
				.setText(IDEWorkbenchMessages.CreateLinkedResourceGroup_browseButton);
		browseButton.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent event) {
				handleLinkTargetBrowseButtonPressed();
			}
		});
		browseButton.setEnabled(enabled);
		setButtonLayoutData(browseButton);
		
		variablesButton = new Button(linkTargetGroup, SWT.PUSH);
