[Fedora-suds-list] Extracting Attributes

[Walter, Patrick A]

I have a web service that requires a complex structure (cartesianVector) to be passed as an argument. 

Here is partial python code.....
    cartesianVector = getCartesianVector(theclient)

    imageTypes = theclient.factory.create("ns0:imageTypes")
    print imageTypes
    durationSeconds = 5400.0
    stepSize = 200.0
    width = 400
    height = 400
    
    print cartesianVector
    
    #Error occurs at this request
    bytes = theclient.service.plotGroundTrack(cartesianVector, durationSeconds, 
                                              stepSize, width, height, imageTypes.GIF)

Here is the structure from a "print cartesianVector".

(cartesianVector){
   attrValues = ""
   date = 272692290.64
   referenceFrame = "J2000"
   units = "STANDARD_METRIC"
   VX = 6306.70073861
   VY = 2986.87361604
   VZ = -3246.75882187
   x = 101062.390714
   y = -5041562.75123
   z = -4446623.59309
 }

When I call the server service I get the following error... suds.WebFault: Server raised fault: 'java.lang.NullPointerException'

Other service methods work, when passing "primitive" types (long, strings) as arguments. Services can also return complex types. 

The service is a Java 1.6 version.

I'm using Python 2.5

THANKS FOR YOUR HELP
