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
.getRequiredFieldBackgroundColor(linkTargetField));
				} else {
					linkTargetField.setBackground(null);
				}
				linkTargetField.setEnabled(createLink);
				if (fileSystemSelectionArea != null)
					fileSystemSelectionArea.setEnabled(createLink);
				if (listener != null) {
					listener.handleEvent(new Event());
				}
			}
		};
		createLinkButton.addSelectionListener(selectionListener);
		createLinkLocationGroup(groupComposite, createLink);
		return groupComposite;
	}
	/**
	 * Creates the link target location widgets.
	 * 
	 * @param locationGroup
	 *            the parent composite
	 * @param enabled
	 *            sets the initial enabled state of the widgets

	private void createLinkLocationGroup(Composite locationGroup,

		Button button = new Button(locationGroup, SWT.CHECK);
		int indent = button.computeSize(SWT.DEFAULT, SWT.DEFAULT).x;
		button.dispose();
