Re: sorting over creation date or some getObjProperty('xyz',REQUEST)

Hello Nils,

as far as I understand you you'd like to order your list by a special field like date, datetime etc.

Why don't you use:

	<dtml-in "filteredTreeNodes(REQUEST, 'ZMSFolder' , 'datetime_' , 'desc' ,  10 )"> 
		...
	</dtml-in>

You can sort using filteredTreeNodes easily with the third parameter (order_by).
We use this on http://www.bonncampus.fm/ and http://www.mondberge.com with no problems.

Sorry if I missed anything and this doesn't help.

Mit freundlichen Grüßen
