[Zope] Re: problem with sort_order (when seting up zwikitracker)

[Robert Rottermann]

Hi Simon,
I was stumbling over that problem also and started to investigate it.
The outcome is, that in Zope 2.4 getattr(REQUEST, variable, default) does
not return the default but dies when variable does not exist.
This "feature" was changed back to its expected behavior in 2.5

I checked 2.43 and 2.44b1
to test it just create a dtml method with:
<dtml-var "_.getattr(REQUEST, 'abc', '')">

What I did to solve the problem is I changed al the "offending" dtl-code to
python scripts where I first test for the existence of a key. That makes
much nicer code anyhow.

Robert
