Means, it doesn't work. If I use fields outside the constructor works, for
example:
class RuleForm(TableForm):
fields = [
TextField(id = 'description', label = 'Description'),
]
def __init__(self, id=None, parent=None, children=[], host_filter=[],
**kw):
super(RuleForm, self).__init__(id,parent,children, **kw)
That works, but I need fields inside the constructor because I want to use
SelectionList or CheckboxList which contents could change in each use of
RuleForm (quering data from database).
I could use a function that returns the children field list and use them
like you said but I prefer to use classes or at least understand why my
approach doesn't work.

Diego
