[Zope] UnpickleableError

[Arne Krug]

Thanks, 
it works with DTMLFile or HTMLFile.
But I still have a general question about the Globals.HTML class.
I tried to include a HTML object in the Boring Product:
__init__....
  self.test = HTML('<table>', globals())

for example and it did not work either. The same "UnpickleableError" 
occurred.
What is wrong with including a HTML object in the product. Isn't it 
more or less just a string....
