Priya,

First, the PTK has its own mailing list, zope-ptk@zope.org;  you
are much likelier to get useful and timely advice there about
PTK-specific issues.

Second, I don't think the region of code in which you have injected
that line needs it;  it exists solely to provide backward-compatibility
with portals created before version 0.8 of the PTK.

Third, I can't see anything about your code which woudl trigger a
syntax error;  typically, in this case, the real error would be
a line or two ahead (opening but not closing a parenthesis, omitting
a comma, etc.

Fourth, you would typically add a new content class in a separate
product, either on the filesystem or in a "through-the-web"
ZClass product;  mixing your stuff with PTKBase/PTKDemo means
you will be forced to deal with lots of merge conflicts (and these
days, I mean *LOTS*).

I would recommend creating a new CVS sandbox, as described in my
"State of the PTK" message today:

  http://lists.zope.org/pipermail/zope-ptk/2001-January/002258.html

Then, move your 'Userdocument' module into a new Product, a "sibling"
of PTKBase and PTKDemo.  Register it just as 'PTKDemo.Document' is
registered, and create a Wizard for it by cloning the Document wizard
and "filing off the serial numbers".

Hope that helps,

Tres.
