Re: [Zope] dtml-var weirdness

Stupid question of the day: This does not seem stupid at all!

Why might the following code result in a KeyError? It does in some contexts under Zope 2.5.0.

<dtml-if expr="REQUEST.has_key('xyz')"> <dtml-else> <dtml-call expr="REQUEST.set('xyz','Hello world')"> </dtml-if>

Sometimes the next line results in a KeyError, value 'xyz':

<dtml-var name="xyz">

In such cases, this works fine:

<dtml-with REQUEST only> <dtml-var name="xyz"> </dtml-with> This appears to be a bug.

When you happen to reproduce it, we may be able to analyse its cause. Dieter
