b/c of a bug that i reported with newFormat=1 and fetching data (http://help.zoho.com/portal/en/community/#Topic/2266000000766017), i changed my code to utilize newFormat=2, hoping that would resolve the issue.

previous code (works like a champ):
http://crm.zoho.com/crm/private/xml/Accounts/updateRecords?ticket=[ticket]&apikey=[key]&newFormat=1&id=[zoho_id]&xmlData=<Accounts><row no="1"><FL val="MyField">MyData</FL><FL val="Modified Time">2010-01-12 11:34:00</FL></row></Accounts>

new code (only changing newFormat from 1 to 2):
http://crm.zoho.com/crm/private/xml/Accounts/updateRecords?ticket=[ticket]&apikey=[key]&newFormat=2&id=[zoho_id]&xmlData=<Accounts><row no="1"><FL val="MyField">MyData</FL><FL val="Modified Time">2010-01-12 11:34:00</FL></row></Accounts>

nope.

it doesn't. is this another bug?

cheers,
