Join multiple Tables including 2 join Tables - database

Question

i try to join multiple Tables in one Query.
My Entitie Relations:
Person
Entities\Person:
type: entity
table: person
manyToOne:
address:
targetEntity: Address
joinColumn:
name: idaddress
referencedColumnName: idaddress
manyToMany:
tags:
targetEntity: Tag
joinTable:
name: persons_tags
joinColumns:
person_idperson:
referencedColumnName: idperson
inverseJoinColumns:
tag_idtag:
referencedColumnName: idtag
Tag
Entities\Tag:
type: entity
table: tag
manyToMany:
sms:
targetEntity: Sms
mappedBy: tag
sms
manyToMany:
tag:
targetEntity: Tag
joinTable:
name: sms_tags
joinColumns:
sms_idsms:
referencedColumnName: idsms
inverseJoinColumns:
tag_idtag:
referencedColumnName: idtag
This is a valid working SQL Statement:
SELECT DISTINCT person.lastname, person.firstname, address.mobileprivate, address.mobilebusiness FROM
`address`,
`person`,
`persons_tags`,
`sms_tags`
WHERE
person.idaddress = address.idaddress
AND person.idperson = persons_tags.person_idperson
AND persons_tags.tag_idtag = sms_tags.tag_idtag
AND sms_tags.sms_idsms = (myINPUT)
Now i try to join the needed Entities in DQL to get the same result:
SELECT DISTINCT s, t, p, a
FROM Entities\Sms s
JOIN s.sms_idsms t
JOIN t.person_idperson p
JOIN p.idaddress a
WHERE s.idsms = (myINPUT)
But i only get an error:
PHP Fatal error: Uncaught exception 'Doctrine\\ORM\\Query\\QueryException' with message '
SELECT DISTINCT s, t, p, a
FROM Entities\\Sms s
JOIN s.sms_idsms t
JOIN t.person_idperson p
JOIN p.idaddress a
WHERE s.idsms = 2' in

How to write a DQL Query like the working SQL Query?
I try to avoid a native SQL Query
Here is a try with the Query Builder:
$qb->select(array('s', 't', 'p', 'a'))
->from('Entities\Sms', 's')
->leftJoin('s.tag', 't')
->leftJoin('t.person', 'p')
->leftJoin('p.address', 'a')
->where('s.idsms = 1');
And the Error Message
PHP Fatal error: Uncaught exception 'Doctrine\\ORM\\Query\\QueryException' with message 'SELECT s, t, p, a FROM Entities\\Sms s LEFT JOIN s.tag t LEFT JOIN t.person p LEFT JOIN p.address a WHERE s.idsms = 1' in /var/www/ci_doc_rem/Codeigniter_Doctrine/source/application/libraries/Doctrine/ORM/Query/QueryException.php:39\nStack trace:\n#0 /var/www/ci_doc_rem/Codeigniter_Doctrine/source/application/libraries/Doctrine/ORM/Query/Parser.php(429): Doctrine\\ORM\\Query\\QueryException::dqlError('SELECT s, t, p,...')\n#1 /var/www/ci_doc_rem/Codeigniter_Doctrine/source/application/libraries/Doctrine/ORM/Query/Parser.php(925): Doctrine\\ORM\\Query\\Parser->semanticalError('Class Entities\\...')\n#2 /var/www/ci_doc_rem/Codeigniter_Doctrine/source/application/libraries/Doctrine/ORM/Query/Parser.php(1561): Doctrine\\ORM\\Query\\Parser->JoinAssociationPathExpression()\n#3 /var/www/ci_doc_rem/Codeigniter_Doctrine/source/application/libraries/Doctrine/ORM/Query/Parser.php(1506): Doctrine\\ORM\\Query\\Parser->JoinAssociationDeclaration()\n#4 /var/www/ci_doc_rem/Cod in /var/www/ci_doc_rem/Codeigniter_Doctrine/source/application/libraries/Doctrine/ORM/Query/QueryException.php on line 49

The Solution was to easy to find.
I've replaced the idname namingconvention just by 'id' for every table / entitie and had a closer look to Picking Owning and Inverse Side.
http://docs.doctrine-project.org/en/latest/reference/association-mapping.html#picking-owning-and-inverse-side
This enabled me to write correct Relations.
A big Problem for me, was to decode the Debug Stack Trace to find my error.
Thanks to anyone who spend time to solve my Problem!
