i am encountering some rather bizarre problems with 'properties' on xt_objects, which are effectively fancy folderish DTML Documents. the problems are two fold... - i call manage_changeProperties on an xt_object within other xt_objects, and at times, it would change the same property, e.g. xt_options, on all the other xt_objects in the same container! this would be magically rectified when i restart the zope server! - the second problem is of a different nature, it's to do with 'Date properties'. i have several date properties set by dtml when an object is created, e.g. xt_expiration_date. however, when i manually change a date property through manage_propertiesForm, it suddenly stops being a date property, e.g. if set through DTML, i can do <dtml-var "xt_expiration_date.year()"> but, i get an attribute error on year, if i change it manually... the code for xt_objects can be found at http://mu2.espnow.com/~zope/xt_object.py and any help would be appreciated. -- best regards, tav tav@espnow.com
