Here is a quick patch for this problem (against 2.9.1). There were two
different problems:
- the id attributes were not generated, because the conditional was reverse.
- unlike xmllib, expat always returns Unicode data, so simply concatenating
binary values generates Unicode objects with non-ascii characters.
For the latter problem, I'm not sure if my patch is enough. But this patch
works with a simple dtml export/import.

I just exported the stock 'standard_error_message' as XML and
re-imported it successfully in a brand new Zope-2_7-branch instance.

Likewise, my import succeeded in a Zope-2_8-instance, both with the XML
file exported from 2.7 and with one created from 2.8.
> Zope 2.9 raises the described UnicodeDecodeError.
My Zope-2_9-branch instance was successfully able to import the XML file
from 2.7, but raises a UnicodeDecode error on the file it produces, as
well as the one created from 2.8. The stack trace here makes it seem as
though Python 2.4.2's expat parser is at fault: it is introducing
non-ASCII characters into the stream where none exist in the source:

['U', '\x03', 'r', 'a', 'w', 'T', '\xcb', '\x04', '\x00', '\x00', '<',
'd', 't', 'm', 'l']
That output seems to me to indicate that the start of the CDATA section
is the problem.

I've just tried again, running with Python 2.4.3c1, because several of
the changelog entries for the release suggest that unicode / encoding /
expat stuff may have been fixed: the decode error is still present.

Can we have a Zope 3.2.1 along with Zope 2.9.2? There are a few bugfixes on the Zope 3.2 branch (e.g. involving widgets, formlib, testbrowser) that are relevant for Zope 2 as well.

Re: [Zope-dev] IMO ZClasses should stay
+1 I have handed systems with a thin ZClass layer on top to semi- developers and they were *easily* able to take it from there. These are people who would never have grokked (and bothered with) disk- based Python development and all the mumbo-jumbo it entails. No other system has anything even remotely like this. People are *blown away* by the power of building objects TTW (define some properties, write a few scripts and templates, done!). Take that RoR, Django, Vignette, Broadvision, ... ;-) Of course ZClasses have their limitations, but I fully agree that this is first and foremost a documentation problem. Stefan On 24.
