[ZPT] determining the value of a folder's property

[robert]

 <li tal:condition=3D"subfolder/navigation | nothing">
avoids an error when navigation does not exist.

to have the folders sorted on an other field than the name you have to crea=
te=20
your own routine in a python script you have to call yourself like:
 <span tal:repeat =3D "subfolder=20
python:here.mysortscript(here.objectValues('Folder'))">

assuming your script has a paramater folders in which you pass the folders =
to=20
sort:

names=3D[]
result=3D[]
for folder in folders:
    names.append(folder.theFieldIWant)
names.sort()
for name in names:
      result.append(dic[name])
return result
