It was very much alike, but you were right ;-).
The difference was that I did a
(sort of cut down pseudocode)
in which case the dtml-in interferes badly with the dtml-with
so turning it around to
which works.
So is this subtle or what ?! But at least it's consistent

Hm. You don't want me to send some of the clobbered stuff I put together
then. Still, I don't see how to do this in a cleaner way in a Python Method
(it will look cleaner, but the voodoo will be about the same unless I'm
badly mistaken).
Thanks (and Kevin also) for your help in sorting this out.

I am using it to render the document, not just get me the code. The
document is a DTMLMethod that renders a Zope install unique id based on the
time.

But it wouldn't totally suprize me.

Yes I bet it (sorry couldn't resist)
thanks again, and i'll let you know if it works. It would be highly
inconsistent if it would work from one product folder (a different from the
current one) and not for the other (the current). So I think this deserves
some more digging.

Thanks for replying Kevin, but it won't work ;-( I tried it ALL, and it _will_not_work_. The nested ZClasses will apparently solve it (I used it elsewhere), but it will get you into trouble in other situations - if you want to add an instance of the nested zclass to an existing instance of that same nested zclass.

[Zope-dev] Recursively adding ZClasses (continued)
Could someone help me understand adding adding ZClasses a bit further? First I had a problem with nested ZClasses, which got me into trouble when I wanted to add ZClasses to each other. So I followed the 'common wisdom' of adding all ZClasses at the top level of the product. THis generally works OK, and you can add ZClass instances to each other from the management interface. So far so good. WHere things go wrong is by recursively adding ZClasses, as in: the following pseudo code for ParticularZClass with some NestedZClasses inside: ( constructor has the following action sequence): create ParticularZClass instance set some properties in somelist set some other properties into REQUEST create NestedZClass instances whatever reading and following every piece of documentation I could get on this (not much), I never got any further than adding the NestedZClasses instances on the _same_ level as the ParticularZClass. No (which contrary to documentation should have the containing product and not the ZClass as the 'whatever' argument) could help me out. The only workaround is to create the ZClass in an auxiliary product, in which case the recursive adding does work. Could someone explain what is happening here (apart from that it's a bug)? And yes, I'll add it to the Collector.
