	 * (3) File name field text does not already end with a '.' and the file
	 * extension specified (case sensitive) <br>
	 * <br>
	 * The file extension will not be reflected in the actual file name field
	 * until the file name field loses focus.
	 * 
	 * @param value
	 *            The file extension without the '.' prefix (e.g. 'java', 'xml')
