Default Object reference not set - WebReference WS

Hi There,
Here's some puzzling one...
I've added a web reference to my project and now i cant't get it instantiated, i always get

'Object reference not set to an instance of an object.' exception.

Here's C# code:

1: OTA_AirAvailRQ OTA_AirAvailRQ_Document = new OTA_AirAvailRQ();
2: OTA_AirAvailRQ_Document.POS.Source[0].PseudoCityCode = "LAS1S210D";

I get the exception on line 2, intellisene displays everthing ok, and it compiles fine, but at runtime it blows.

Any ideas, is it something that i'm forgetting of ?
Thanks a lot.

Something doesn't look right with your syntax:

What is the POS property of the ORA_AirAvailRQ class?

Is ORA_AirAvailRQ the web proxy class? I don't see any method calls on that. Generally, you should be making a method call and then work with what is returned.

There is a high probability that the source of the error is coming from you array element Source[0] not having been initialized to any object.

Check that the array contains something
