I may have missed this being addressed somewhere, but I'm having the
following problem.
The generic marshaller will not marshal new style classes. I've seen
reports of similar problems, but no solutions.
---start code---
For example:
>>> class WillWork:
... pass
...
>>> class WontWork(object):
... pass
...
>>> will = WillWork()
>>> wont = WontWork()
>>> import xml.marshal.generic
>>> xml.marshal.generic.dumps(will)
'<?xml version="1.0"?><marshal><object id="i2" module="__main__"
class="WillWork"><tuple></tuple><dictionary
id="i3"></dictionary></object></marshal>'
>>> xml.marshal.generic.dumps(wont)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "C:\Program
Files\Python24\Lib\site-packages\_xmlplus\marshal\generic.py", line 59,
in dumps
L = [self.PROLOGUE + self.DTD] + self.m_root(value, dict)
File "C:\Program
Files\Python24\Lib\site-packages\_xmlplus\marshal\generic.py", line 104,
in m_root
L = ['<%s>' % name] + self._marshal(value,dict) + ['</%s>' % name]
File "C:\Program
Files\Python24\Lib\site-packages\_xmlplus\marshal\generic.py", line 92,
in _marshal
return getattr(self, meth)(value, dict)
AttributeError: Marshaller instance has no attribute 'm_WontWork'
---end code---
Has anyone found a fix for this, or is anything planned ? I've raised a
bug on sourceforge.
Thanks,
Mark
