For example, the state implementation can be done as follow:

	// Input Attribute
	private static final TextBoxAttribute inPIId = new TextBoxAttribute("PI_ID", "Payment Instrument Id", false);
	private static final TextBoxAttribute inOutputDateFormat = new TextBoxAttribute("OUTPUT_DATE_FORMAT", "Override default output date format", true);



	// Output Attributes
	private static final OutputAttribute outAcctNumber = new OutputAttribute("PI_BANKACCT_ACCTNUMBER", "Account number");
	private static final OutputAttribute outHolderName = new OutputAttribute("PI_BANKACCT_HOLDERNAME", "Account holder name");



	private static Attribute[] stateAttr = new Attribute[] { inPIId, inOutputDateFormat, outAcctNumber, outHolderName};




	protected Attribute[] getStateAttributes() {
		return stateAttr;
	}
