[Fedora-suds-list] list (apparently) being sent as '[]' instead of []

[Tom von Schwerdtner]

Greetings folks, I'm trying to figure out whose fault this is and  
would appreciate some input.

In short, I have a service call that takes a FilterRules type as an  
argument (pulled from the client factory), which is configured as  
follows:

 >>> print filter

(FilterRules){
	marketClassIds[] = <empty>
	vehicleTypes[] = <empty>
	}


The spec for this service says that marketClassIds should be an array  
of integers,  however when I assign it to an array as follows:

 >>> filter.marketClassIds = [1, 2]
 >>> print filter

(FilterRules){
	marketClassIds[] =
		1,
		2,
	vehicleTypes[] = <empty>
	}

and I submit it, I get the following error:

	suds.WebFault: Server raised fault: 'JAXRPC.TIE.01: caught exception  
while handling request: deserialization error:  
java.lang.NumberFormatException: For input string: "[1, 2]"'

FWIW, I have seen (but not executed, yet) PHP code for the service  
that simply assigns an empty array to marketClassIds, doing so with  
python results in a similar input string error.

So it seems the server is interpreting the marketClassIds as the  
__str__ of the array, and not as an actual array.  If I set  
marketClassIds to a non-array integer, eg:

	filter.marketClassIds = 1

It works.

So, my question is, am I doing something wrong, is suds doing  
something wrong, or is the server I'm hitting doing something wrong?   
Any tips on further debugging this?  I'd love to provide working  
samples but unfortunately this is a proprietary service.

I can give more information if needed, I'm not too familiar with SOAP  
so I wasn't sure what to provide.

Regards,
Tom
