Re: [Simple-support] NullPointerException for similar Element Names with different @Paths

[amit.shipra <ami...@rb...>]

Please ignore. My bad. Didn't read the document carefully. This solved the
problem.

	@Element(name="sourceSystem[1]")
	@Path("ns0:book/ns0:identifier")
	private String bookSourceSystem="system1";


	@Element(name="sourceSystem[2]")
	@Path("ns0:trader/ns0:identifier")
	private String traderSourceSystem="system2";
