[Zope-dev] Calendar tag 0.9.6 breaks with 2.2.0b3??

[Dr. Ross Lazarus]

Thanks for the help.

Summary:
CalendarTag works fine in 2.1.6 but is broken in 2.20b3.
__call__ is mapped to render(self,md) - this is the same for all dtml
tags AFAIK.

The point that I find hard to understand is that namespace in DT_Util
has changed from 2.1.6 as follows

===========2.1.6==================
class namespace_: 
    pass

def namespace(self, **kw):
    """Create a tuple consisting of a single instance whos attributes
are
    provided as keyword arguments."""
    r=namespace_()
    d=r.__dict__
    for k, v in kw.items(): d[k]=v
    return r,

========2.2.0b3============
class namespace_:
    __allow_access_to_unprotected_subobjects__=1

def namespace(self, **kw):
    """Create a tuple consisting of a single instance whos attributes
are
    provided as keyword arguments."""
    return apply(self, (), kw)

Now, I can easily put the old definition back and it might work - but
I'm not in a position to understand why the method has changed from what
looks like a simple dictionary construction to the apply function -
which doesn't seem to have anything to do with the namespace_ class !!
