Samisa...

Actually, I was doing a little sleuthing and found there is a problem in the
SoapDeSerializer.cpp file in the getBasicArray method.

When I looked this morning over at the axis-c-dev mailing list, it seems
someone else has reached the same conclusion:


QUOTE:
[AXIS C++ 1.3] Bug in SoapDeSerializer::getBasicArray when there is more
than one array

Using axis-c 1.3, I could not get these two vectors, I could get only
one of them.
After some investigation, I found that
SoapDeSerializer::getBasicArray() always get the first next node and after
some
debug, I discovered that the next node was </docsArray> which failed in all
cases.

In order to get the next node not null, I patch the method :

I implemented the same change on my end, and now the code works correctly.
I would concur with Julien Lemoine that this is a necessary fix.

Thanks,
Rob
