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/misc/ContainerSelectionGroup.java
setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
		Label label = new Label(this, SWT.WRAP);
		label.setText(message);
		label.setFont(this.getFont());
		if (allowNewContainerName) {
			containerNameField = new Text(this, SWT.SINGLE | SWT.BORDER);
			GridData gd = new GridData(GridData.FILL_HORIZONTAL);
			gd.widthHint = widthHint;
			containerNameField.setLayoutData(gd);
			containerNameField.addListener(SWT.Modify, listener);
			containerNameField.setFont(this.getFont());
			
			containerNameField.setBackground(FieldAssistColors
					.getRequiredFieldBackgroundColor(containerNameField));
		} else {
			
			new Label(this, SWT.NONE);
		}
		createTreeViewer(heightHint);
		Dialog.applyDialogFont(this);
	}
	/**
	 * Returns a new drill down viewer for this dialog.

	protected void createTreeViewer(int heightHint) {
