Third party web services "object not set to an instance of an object"

[aaa]

I am using a third party provider for Travel related web services. These
services are not very well documented and I am having to wing my way thru
nearly every one.

Some I can pull data from just fine others bomb when assigning criteria to
the body of it's request object ("object not set to an instance of an
object").

I am essentially creating nodes programatically to buld the XML that gets
pumped to the SOAP call. Has anyone run across a simi.ar problem. I am
creating the criteria "objects" so the error is not extremely helpful and I
feel that I am missing something simple.

I have run into this error message a number of times. Every time I have
tracked it down to 1 of 2 things:
1. A catch statement that tries to trap an error that is not available, for
example, and exception innerexception.message, which may not necessarily be
available,
or
2. A completely unhandled exception in the code.

If I understand you correctly, this is probably not much help since you
do not have direct access to the code.

You could try 2 things, run your program in "debug" mode to see if it
sheds some light on the error, or try to use the reflection classes to view
what is in the code.
