Multiple file upload Symfony2 throwing exception - php

Question

Hello I'm trying to make a file upload with a oneToMany relation between an Annonce and some images; So an Annonce can contain 0 or more images and an image is still attached to an Annonce. I think everything is ok with my entities but I get this error when I submit the form.

}
And I have the following error at the form submit :
Neither the property "images" nor one of the methods
"addImag()"/"removeImag()", "addImage()"/"removeImage()",
"setImages()", "images()", "__set()" or "__call()" exist and have
public access in class "MDB\AnnonceBundle\Entity\Annonce".
I don't understand cause these getter exist in my entity. Anyone have an idea?
Thanks

This error was logic. Just use a collection field type solved the problem
