[Zope] PropertyIds

[RC Compaan]

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.

<dtml-var "MyDoc.propertyItems()"> returns a list of key-value pairs
[('Key1','Value1'},('Key2','Value2')]

to access the values of each key sequentially i tried:
<dtml-in "MyDoc.propertyItems()">
  <dtml-let s="_['sequence-item']" key=s[:1] value=[1:]>
  <dtml-var key>:<dtml-var value><br>
</dtml-in>

But this just returns "k" and "ey" resulting in a slice of the keyname.
