Collection Filters

[stood]

In the doc, it is writen to use the collection filters for to transform json value to an object instance.

But if I use the example: https://github.com/pomm-project/ModelManager/blob/2.0/documentation/model_manager.rst#collection-filters

I have an error `` `Warning: trim () expects parameter 1 to be string, object given```

Because the hydrationPlan using the converter Json but the value is an ObjectInstance

Ok, a filter does not override a converter, the documentation is wrong. Thank you.
