Hi, I have several zope folders on the FSDV and I want to display their titles in a certain order with a ZPT. Since folders on FSDV can not have property of their own, I created a FS property object, whose id is 'property', in each of the folders. And each 'property' objects contains a property 'menu_order', according to which the folders should be sorted. I try to use the following code to sort the folders: <ul tal:define="folders here/get_folders; sort_on python:(('property/menu_order', 'cmp', 'asc'),); sorted_folders python:sequence.sort(folders, sort_on)"> But it seems the sort condition can not contain path expression to access 'property/menu_order'. It takes the whole as a property of the folder object and wouldn't treat 'property' as an object contained in the folder and get its property 'menu_order'. As a result, no sort is performed. Is there any solution to this except for writing a custom sort function of my own? Thanks, Hong Yuan
