When running over a list of pairs, dmtl-in automatically splits pairs
into sequence-key and sequence-item

RE: [Zope] PropertyIds
Very clear, thanks. Really appreciated.
Well i guess the topic was never about propertyids, but i can only tell that
now. Still working with properties i find the following trouble.
returns a list of key-value pairs
[('Key1','Value1'},('Key2','Value2')]
to access the values of each key sequentially i tried:
:
But this just returns "k" and "ey" resulting in a slice of the keyname.

Re: [Zope] PropertyIds
Thanks Rik it works. I've noticed in some cases that one puts empty brackets at the end of certain zope object methods. Is that there for methods that can take parameters? [rh]Um, not quite, it has to do with the way of calling the object methods in question. DTML has two ways of calling: by name and through expressions. 1. The 'normal' Zope way of writing things is . This is shorthand for . 2. The other way is . This is shorthand for . Everything inside the expression is treated as a python expression. If you call it without the brackets, you're just referencing the method. If you try that in a DTML Method and look in the source of the diplayed document you'll see something like . If you want to _call_ the method, you'll have to add the brackets (with or without arguments). Hope this is clear.

[Zope] PropertyIds
I have a very simple documentclass in very simple structure in method that should return the properties of the document: // RESULTS is a ZClass Object Manager // tmp is a document with an id equal to the cookie During the application i add properties to the document and want to display them with the above method. The Property ids does not get shown though. I've tried: and also: But no luck. How can this work?
