Unexpected token "[" at position.

[drbarzaga]

I am working on a project where I use this bundle to translate the entities and a bundle of Datatable to show the results in tables, it turns out that when I have an entity that has datatables translations it tells me that to show the related values of 1 an is used like this:

-> add ('translations.name', Column :: class, array (
                 'title' => $ this-> translator-> trans ('role.roles'),
                 'data' => 'translations [,] .name'
));

But if I do this it gives me an error like this:

Could not parse property path "[translations] []". Unexpected token "[" at position 14

Does anyone have an idea why?
