Good - Thanks to gogo for sending me his 'walkthrough' notes

This sounds like the filter is filtering them out.  I would try two things:
1) Verify you can add a different type and have it show up (like a Document)
2) You may have the incorrect meta type - actually, the copy I sent you
probably
has this typo - Verify that the meta type name that you use in the
types_tool
definition has the same name as that in your class definition. (This should
be
PortalPollType and not PollClassType if you are following the steps
verbatim.

I don't believe you have to add CMFCatalogAware to make you content
appear in the catalog any longer, (I think that used to be the case).
Simply by deriving from PortalContent should work.  Items that are
created with the tutorial will appear in the catalog and are searchable
for question or answers.

You are absolutely correct.  This tutorial has evolved over time, and
it makes no longer makes sense to derive *content* from *Tool* classes.
Shane pointed this out to me and I updated the tutorial a little while back.
Tool based classes exist so that you can change the 'behavior' of the
portal by overriding or enhancing the tool.  Sorry if this caused you some
problems.
