Child entities in document not loading

[John Ament]

All,

So I think I have my first issue figured out, need to add terms to the
default search.  That's fine.

New issue is that I'm trying to load child entities in with my entity.

I added the appropriate fields to solrconfig.xml

    <field name="sections" type="string" indexed="true" stored="true"
multiValued="true"/>
    <field name="colors" type="string" indexed="true" stored="true"
multiValued="true"/>
    <field name="sizes" type="string" indexed="true" stored="true"
multiValued="true"/>

And I updated my document to match

    <document>
        <entity name="product" query="select product_id, product_id as
id,vendor_label_name, sku2, style,product_name,delivery_time,regular_price,
copy_field,bullet1,bullet2,bullet3,bullet4,bullet5,bullet6,
bullet7,bullet8,bullet9,bullet10,bullet11,bullet12 from product_v where
status_code = 'ACTV' and regular_master_variant in (2,1)">
            <entity name="section_product" query="select section_title as
sections from section s, section_product sp where sp.section_id =
s.section_id and sp.product_id='${product.product_id}'"/>
            <entity name="color_product" query="select distinct
aev.enum_value as colors from product_attribute_enum
pae,attribute_enum_value aev, sub_product sp where pae.product_id =
sp.sub_product_id and pae.attribute_type_id = aev.attribute_type_id and
pae.attribute_value_id = aev.attribute_value_id and pae.attribute_type_id =
107 and sp.master_product_id = '${product.product_id}'"/>
            <entity name="size_product" query="select distinct
aev.enum_value as sizes from product_attribute_enum pae,attribute_enum_value
aev, sub_product sp where pae.product_id = sp.sub_product_id and
pae.attribute_type_id = aev.attribute_type_id and pae.attribute_value_id =
aev.attribute_value_id and pae.attribute_type_id = 108 and
sp.master_product_id = '${product.product_id}'"/>
        </entity>
    </document>

So my expectation is that there will be 3 new fields associated with it that
are multivalued: sizes, colors, and sections.

The full-import seems to work correctly.  I get the appropriate number of
documents in my searches.  However, sizes, colors and sections all come up
null (well, I should say they don't come up when I search for them).

Any ideas on why it won't load these 3 child entities?

Thanks!
