Я использовал следующий пример для реализации:
У меня есть Entity для страницы и для тэгов к страницам:
MyModule\Entity\Page
MyModule\Entity\Tag
Для одной страницы можно указать N тэгов.
На странице добавления страницы не удается динамически добавлять тэги для страницы. Подскажите что я делаю не так.
Привожу листинг основных файлов:

Ну и наконец представление add.twig:
{% extends 'layout/layout.twig' %}
{% block content %}

<div>
{{ form().prepare() }}
{{ form().openTag(form)|raw }}
{% for element in form %}
{% set attributes = element.getAttributes() %}
{% if type != 'hidden' and type != 'submit' %}
<div class="field">
{% endif %}
{% if attributes.type is defined %}
{% set type = attributes.type %}
{% else %}
{% set type = '' %}
{% endif %}
{% if type != 'hidden' and type != 'submit' %}
<label for="{{ element.getName() }}">{{ element.getLabel() }}: </label>
{% if attributes.required is defined %}
<abbr title="Обязательное поле">*</abbr>
{% endif %}
{% endif %}
{% if type == 'text' %}
{{ formInput(form.get( element.name ))|raw }}
{% elseif type == 'textarea' %}
{{ formTextarea(form.get( element.name ))|raw }}
{% elseif type == 'select' %}
{{ formSelect(form.get( element.name ))|raw }}
{% elseif type != 'hidden' and type != 'submit' %}
{{ formRow().setInputErrorClass('error').render(form.get( element.name ))|raw }}
{% endif %}
{% if type != 'hidden' and type != 'submit' %}
</div>
{% endif %}
{% endfor %}
{{ formCollection(form.get( 'page' ).get( 'tags' ))|raw }}
{{ formRow(form.get('submit'))|raw }}
{{ form().closeTag(form)|raw }}
</div>
{% endblock content %}
Подскажите что нужно поправить, чтобы при создании Page можно было динамически добавлять сколько угодно Tag ?
