This error is easy of replicate:

1. I transfered my contacts from Outlook using the ZOC (I dont know if this matters)
2. I asked zimbra for open a contact to modify its data entry (ajax version)
3. I attempted to add a new phone number
4. I fill the field with the new phone number, and hoo hooo... SAVE button is disabled.
5. In order to enable the button, I made some changes on other fields, so button turns enabled.

6. Regardless SAVE button is now enabled to save the changes, zimbra does not store the changes.

Okay, problem is in the table. Someone knows how to fix it up?

Thank you :-PoKo;:-
