Symfony3 : Lost values when saving data in database with collection into collection - sql

Question

I try to create a tree structure for a catalog.
First the user creates the catalog with basic informations (name, code, validity period, type, etc.). Then, I redirect user in another form to create the tree structure.
The catalog can have multiple levels.
The levels can contain multiple products (named here "Model").
So, in my tree form, I have a collection of levels.
And in the level collection form, I have a collection of models.
In other words, I have a collection into another collection.
I don't manage to save my several entities in database. It losts the model values (second collection) when I do $em->flush(); in my controller. I have an integrity constraint violation on the composite key of CatalogModel entity (which is composed of the level id and catalog code).
However, Catalog, CatalogLevel and CatalogModel are well persisted. There are both filled with correct datas.
So I don't understand what I'm doing wrong....
Catalog Entity : Note that I don't use an auto generated Id. The Code is the id, and it is provided by the user when he creates the catalog.

CatalogLevel entity : I don't use an auto-generated ID either. Level as a composite key composed with level id and catalog code. The id is generated in JS when I create a level with the add button in the form. Remember, levels are a collection form.

I don't understand why model values are lost... Please help !
PS : If I create just levels in my tree, with no models, levels are saved in database. No error. So, I have a problem with models.
