Hi everyone,

I've been working away on a ZClass-based product that will provide a searchable job board for our Human Resources Dept. here at school. Things were going along fine until, it seemed, out of the blue I started getting an error message about an "Invalid Date-Time String" and a lengthy traceback. I'm wondering if anyone can glean anything from the traceback. Is this one of those obvious errors that I'm just missing? I'm really puzzled. Any advice would be appreciated. Here's the traceback:

You're trying to change the zclass properties after creating it but you're not passing in a valid date time string and hence you're getting this error. Make sure the string you're passing in conforms to a date time format. (check ZOPE_HOME/lib/python/DateTime/DateTime.py for the supported formats), or just cast it explicitly like <dtml-call "REQUEST.set('date', DateTime('datestring'))">. I've noticed some behavior earlier today where i change all my zclass properties in a manage_changeProperties (depends on where) even ones not listed in the request. if this is your problem and you don't have date_time string set in the REQUEST you can try explicitly passing in a dummy date time string (ZopeTime or distant past), or setting it to its default value, <dtml-with object> <dtml-call "REQUEST.set('Date', date)"> </dtml-with> i'd chuck this into the Collector/Tracker. i'm sure others have good solutions.
