1779025 - CardDAV address book contacts are not editable when having multiple E-Mail address entries but none has "PREF=1" as attribute

Status: RESOLVED DUPLICATE of bug 1777214

(Thunderbird :: Address Book, defect)

Description

[Lukas.Wringer]

Steps to reproduce:

I configured an existing CardDAV address book (containing contacts). (SOGo, vCard 3.0) and tried editing an existing contact with multiple E-Mail addresses.

Actual results:

Clicking on 'Edit' just does nothing.

As far as I have found this is caused by not having an entry with PREF=1.

Depending on the contact different errors are shown in console - in my test-case this message appears every time I try clicking on edit:

17:15:33.933 Uncaught TypeError: defaultEmail is undefined

The exported vCard from Thunderbird :

BEGIN:VCARD
VERSION:3.0
UID:XXX-XXXXXXXX-XX-XXXXXXXX
CLASS:PUBLIC
PROFILE:VCARD
PRODID:-//Inverse inc./SOGo 5.7.0//EN
N:;Name
FN:Name
X-MOZILLA-HTML:FALSE
EMAIL;TYPE=work:[e-mail]
EMAIL;TYPE=home:[e-mail]
END:VCARD

Expected results:

The contact should be editable - I think the best option is to use the first E-Mail address as preferred when no option is configured as a fallback - as PREF=1 is an optional field:
rfc6350 section-6.4.2: Special notes: The property can include tye "PREF" parameter to indicate a preferred-use email address when more than one is specified.
