[Zope] DTML Document ids

[Derek S. Wilson]

Are you putting this in a DTML Document, or a DTML Method? AFAIK, that
won't work unless it's in a method.

Thanks,
Derek Wilson

maybe, but..

... if I use the above I get an error (id does not exists as attribute
of the DTML Document istance) ...

... and if I use:
<dtml-var "sequence_item.getId()"><br/>

I get the expected id.

Now, can you please elaborate a bit (or point me to some doc) on why I
should use the getId() method  instead of the id attribute? It happens
that I have exactly this bad habit and I have quite a lot of code where
I use id attributes :-(

Thank for the reply,
