write a small script (python),

get_index try: my_index = context.index except: my_index = 0 return my_index

now with <tree .. sort=get_index>

I did it with plain DTML: <dtml-if "_.hasattr(aq_explicit,'dirIndex')"><dtml-return dirIndex> <dtml-else><dtml-return "0"> </dtml-if> but didn't work. No error, but also no correct sorting. The order of things is different from that when using no sort= attribute, but I couldn't figure out what kind of order it is :-( Even when I just return the id in my dtml method, where you would expect tree-tag to sort things by id, it doesn't do the sort correctly. So, anybody an idea what's going on here? -- Lars Heber, mailto:Lars.Heber@t-systems.de T-Systems, debis Systemhaus GEI GmbH, Geschaeftsstelle Sachsen
