The question then is: what's the difference between the two? Are there fields in one that aren't in the other? Are they processed by different methods? Without a traceback, there's not a lot to go on, but I'd start troubleshooting by picking apart the differences between the forms. Enabling a traceback might be a good idea too.

Hi,

I'm using Zope-2.6.1 with Python-2.1.3 on Debian GNU/Linux. I've created a custom "folder based" Zope product with several custom properties of several types : string, date, text, selection, boolean and tokens. When I try to update these properties from the common "Properties" page, I can read properties values but when I try to submit the form, Zope raises an exception : "String error: string index out of range".

But everything is OK if I update the same properties from a custom form available to my site users !!

This exception is not logged to the site error log, so I can't get any traceback.

Thanks for any help.
