Read data with relation = Multiple matching records

Hello,
​
I try to connect 2 tables with the multiple matching records relation, but there's someting I do wrong because I've got "an error in my SQL syntax near 'FROM `#__contentitem_tag_map` AS `map` WHERE `map`.`content_item_id` IN ('1', '"
​
It was working fine on CF v6, but I can't reproduce it on CF v7.
I think I missed something.
I join the 2 backups (v6 and v7).
​
Does anyone know how to do this sort of relation between to tables ?

does it work when you chnge the relation type to "one matching record, fkey in this model" ?

Hello Max,
​
Yes, it does work when the relation type is "one matching record, foreign key in this model".
Here the result in the debug with this type of relation :

[var] => Array
                (
                    [0] => Array
                        (
                            [contact] => Array
                                (
                                    [id] => 70
                                 )

                            [map] => Array
                                (
                                   [content_item_id] => 70
                                   [tag_id] => 2
                                )

                        )

                    [1] => Array
                        (
                            [contact] => Array
                                (
                                    [id] => 70
                                 )

                            [map] => Array
                                (
                                    [content_item_id] => 70
                                    [tag_id] => 4
                                )

                        )

​
What I need is this result :

[var] => Array
                (
                    [0] => Array
                        (
                            [contact] => Array
                                (
                                    [id] => 70
                                 )

                            [map] => Array
                                (
                                  [0] => Array
                                    (
                                    [content_item_id] => 70
                                    [tag_id] => 2
                                    )
                                  [1] => Array
                                    (
                                    [content_item_id] => 70
                                    [tag_id] => 4
                                    )
                                )
                        )

It was working on CFv6 with the "multiple matching records" relation, but with CFv7, I've got an error.
Maybe it is the syntax in the "equation" that is not correct.
I have tried with :
map.content_item_id = contact.id (field)
map.content_item_id IN contact.id (field)
map.content_item_id = contact.id (value)
map.content_item_id IN contact.id (value)
But I've got the same error (the one in the first message) with all syntaxes.

Thanks !
I will wait the official update.
