[Pywebsvcs-talk] ZSI: serializing and nested structures

[Karsten B. <ka...@ka...>]

Hi,

regarding to some other postings to this list the following code
should work, but throws an exception. Why?

***********
from cStringIO import StringIO
from ZSI import *

class Level1:
	def __init__(self, parm1=None, parm2=None):
		self.parm1 = parm1
		self.parm2 = parm2
Level1.typecode = TC.Struct(Level1, [ TC.String('parm1'), TC.String('parm2') ], 'Level1')

class Level2:
	def __init__(self, level1=None):
		self.level1 = level1
Level2.typecode = TC.Struct(Level2, [ Level1.typecode ], 'Level2')

myout = StringIO()
level1 = Level1("parameter1", "parameter2")
level2 = Level2(level1)

sw = SoapWriter(myout)
sw.serialize(level2) #exception, but serializing level1 works 
sw.close()
print myout.getvalue()

**************

Traceback (most recent call last):
File "test.py", line 20, in ?
sw.serialize(level2) #exception, but serializing level1 works 
File "ZSI/writer.py", line 72, in serialize
typecode.serialize(self, pyobj, **kw)
File "ZSI/TCcompound.py", line 144, in serialize
self.cb(sw, pyobj, **kw)
File "ZSI/TCcompound.py", line 174, in cb
raise Exception('Serializing %s.%s, %s %s' %
Exception: Serializing Level2.Level1, AttributeError 'NoneType' object has no attribute '__dict__'

**************

Thanks,
Karsten
