Sorry, shoulda mentioned, this error came from 2.2.4, and apologies for
not testing against at least 2.2.5 first, I managed to miss its release
entirely... (I still haven't gotten around to installing it so I can't say
if it's mysteriously fixed in 2.2.5 or what.)

On that note, if I have a (different) 2.1.6 site I'm about to take down
and migrate to a current release, should I go with 2.2.5 or try to track
2.3 CVS? I was planning on going with 2.2.x, but if the version in cvs is
_more_ mature than the previous release...

Thanks,

jim

I tried to reproduce this in Zope 2.3 CVS.

I had to replace "_" by "_vars", as "_" gave me
a "NameError: _" (do not know why), but otherwise,
it worked.

I got your error, too, when I tried 'branches_expr="y"',
but that is expected, because in this case, the
expression evaluates to a DTML method and does not
have a "__getitem__" as required by "tree".

[Zope] dtml-tree and a filtered objectValues

2001-01-09 Thread Jim Hebert 

OK, this works:

My DTML Method, "y":


foo


If I change z to read as follows, it breaks:


foo


where y is a DTML Method simply containing



The error I get is:

  Error Type: AttributeError
  Error Value: __getitem__

This is my boiled down example. The real need for this is because I don't
wish to use the full objectValues list, I have another DTML Method which
does this:











So, for those who are interested in the story, I've been using NFGnav, and
have a fair amount of effort invested in marking things as Reference in
NFGnav or not, and would like to move to a dtml-tree which respects that
setting. The dtml method above gives me a subset of objectValues, those
which are maked 'Reference in NFGnav.'

Note, also, that this works (stolen from someone on zope.org's tips for
debugging a tree):

 
  <>
   
<>
   
 

where nfgObjectValues is the dtml method above.

Any help? Is this a bug in dtml-tree, given that it pukes on something
that dtml-in doesn't?

Thanks,
jim
