QueryAjaxModelLoader and additional filters

[pankus]

I follow the instruction from the official documentation for form_ajax_refs

form_ajax_refs = {
    'active_user': QueryAjaxModelLoader('user', db.session, User, filters=["is_active=True", "id>1000"]) 
}

yet if I try to pass filters to the QueryAjaxModelLoader the following error message exits:
sqlalchemy.exc.ArgumentError: Textual SQL expression 'is_active=True' should be explicitly declared as text('is_active=True')

If you do what the error recommends, does the problem go away? Is this a documentation issue (presumably with newer versions of SQLAlchemy), or a bug in flask-admin?
