<dtml-call "['parent_id'].manage_change properties ({ 'children' : children })">
the ['parent..] is a subscript to... nothing! try to change it to:
thanks for that I noticed an even dumber thing: it should've read manage_changeProperties I have yet another stupid question and realise that I need to go through some more examples, I have been on zope.org for a while and lots of things nearly answer my questions but I am not bright enough to fill in the gaps! Zope really makes me feel dumb! So one last question for the night. I have a folder with an property called "firstchildren" (int) that I am using as a variable The folder is called "addaline", inside that folder is another folder called "lines". I want to have a method in "lines" that updates the value of "firstchildren". I have tried: <dtml-call "REQUEST.set('firstchildren', firstchildren+1)"> and since then tried using Parent and manage_editProperties... I just can't get it right! Is there a good example that I could look at, I am not even quite sure what to search for on zope.org thanks so much, apologies if this is annoying, I'll calm down soon I am sure! josh oN
