Instead, it get a "Python Method". Explanation: "id" is often a method returning a string, not directly a string. Sometimes, i.e. for some classes, it is the string itself. You may use "_['id']". This is equivalent to "id()", if "id" is callable and to "id", if it is not.

I thought I'd seen it all when it came to Zope being bad, but this is
TRULY horrible, it even beats (_,_.None,...) and I thought that would
never happen...
Can someone please tell me why folder.id is a method and
everything-else.id is a string?
Should I chuck this in the collector? (I think I will anyway! :P)
Excuse me while I go off to be sick ;-)

Looks like the 'id' of something along the line is a method rather than a
string. Try "_.getitem('id', 1)".
