Cannot change date value

Hi to all, I have an issue with a date field. I have mapped the dob userprifile field in Joomla to a custom filed "date if birth" in Moodle type date.
When a user register in Joomla the date of birth in Moodle is 01-01-1970. If I change the value in Joomla nothing appened, but if I change that value in Moodle also changes in Joomla properly.
If I try to update profiles of Moodle from Joomdle, I get this warning:

Notice: Undefined index: in /home/format/public_html/administrator/components/com_joomdle/helpers/content.php on line 571
Notice: Undefined index: in /home/format/public_html/administrator/components/com_joomdle/helpers/content.php on line 580

And the date not change.
I also tried to map dob field to a text custom field in Moodle and the value passed to Moodle it's the correct timestamp
I have updated all to the latest version: Joomla 3.7, Moodle 3.2.3+, Joomdle 1.1.2

Hi. Thanks for the info.

I checked and it seems Joomla changed the database format for this field recently. I have done a change that seems to fix joomla to moodle sync. It will be included in nex release.
If you want to do it yourself now, here are instructions:
File: administrator/components/com_joomdle/helpers/mappings.php
Function: get_field_value_joomla16
Before the last line with the return statment, add:

YES It works. Thank you very much!!!

Great, thanks for the feedback.
