Joomla 3 form field set size not working

Question

This my field declaration for my component:

<metadata>
    <layout title="COM_VIAE_CONTACT_VIEW_DEFAULT_TITLE">
        <message>
                        <![CDATA[COM_VIAE_CONTACT_VIEW_DEFAULT_DESC]]>
        </message>
    </layout>
    <!-- http://docs.joomla.org/Standard_form_field_types -->
    <fields name="request">
        <fieldset name="request">
            <field name="NO_RECEIVERS_ERROR_STRING" type="text"
                label="NO_RECEIVERS_ERROR_STRING_LABEL"
                description="NO_RECEIVERS_ERROR_STRING_DESC"
                default="Er zijn geen ontvangers configureerd!"
                required="true" size="100">
            </field>

The size="100" attribute is not taken into account when I look at the admin page of this component.

What am I doing wrong?

Joomla 3.x use Bootstrap 2.3.2 in the admin area.

So, add a class option to your XML for your field, e.g. here's the definition of a textarea note the span6 in the class attribute:

<field
    name="file_exclusions"
    label="COM_EASYSTAGING_LOCALSITE_FILE_EXCLUSIONS"
    description="COM_EASYSTAGING_LOCALSITE_FILE_EXCLUSIONS_DESC"
    type="textarea"
    class="inputbox span6"
    default=""
    rows="10"
    cols="50"
/>
