Hello guys, sorry for the bad English found the error during a necessity and would like to post the solution.

Below is an example of my yml relationamento a many to many.

manyToMany:
centroCustos:
targetEntity: Album\Entity\CentroCusto
cascade: ["persist", "merge"]
inversedBy: unidades
joinTable:
name: unidade_centro_custo
joinColumns:
idunidade:
referencedColumnName: idunidade
onDelete: cascade
inverseJoinColumns:
idcentrocusto:
referencedColumnName: idcentrocusto
idpais:
referencedColumnName: idpais
idmundo:
referencedColumnName: idmundo
onDelete: cascade

Well this example is generating this code.

/**

• @var \Doctrine\Common\Collections\ArrayCollection
  *
• @ORM\ManyToMany(targetEntity="Album\Entity\CentroCusto", inversedBy="unidades", cascade= {"persist","merge"}

  )

• @ORM\JoinTable(name="unidade_centro_custo",
• joinColumns= { * @ORM\JoinColumn(name="idunidade", referencedColumnName="idunidade", onDelete="cascade") * }

  ,

• inverseJoinColumns= { * @ORM\JoinColumn(name="idcentrocusto", referencedColumnName="idcentrocusto") * @ORM\JoinColumn(name="idpais", referencedColumnName="idpais") * @ORM\JoinColumn(name="idmundo", referencedColumnName="idmundo", onDelete="cascade") * }
• )
  */

Notice that Doctrine 2 is not putting commas to separate JoinColumns.

So looking at the source code I found the following code and put it solved my problem.

The changes was performed in EntityGenerator.php line 1090.

$arrJoins = array();
foreach ($associationMapping['joinTable']['joinColumns'] as $joinColumn)

$lines[] = implode(",". PHP_EOL, $arrJoins);
$lines[] = $this->spaces . ' * },';
$lines[] = $this->spaces . ' * inverseJoinColumns={';

$arrJoinsInverse = array();
foreach ($associationMapping['joinTable']['inverseJoinColumns'] as $joinColumn)

$lines[] = implode(",". PHP_EOL, $arrJoinsInverse);
$lines[] = $this->spaces . ' * }';
$lines[] = $this->spaces . ' * )'; }

I hope you understand what I'm trying to say, for you do not know if this error occurred, but if there ocorrei is one possible solution.

Thank you.
