James Dyer commented on SOLR-3842:
----------------------------------
>From Stackoverflow:
I'm trying to perform a full-import with document configuration similar to the
following:
<document>
<entity name="parent" query="select * from parent_table" >
<field name="id" column="ID" />
<entity name="child" query="select * from child_table where PARENT_ID =
${parent.ID}" transformer="ClobTransformer" >
<field name="${child.FIELD_COLUMN}" column="VALUE_COLUMN"
clob="true" />
</entity>
</entity>
</document>
Let's say the field/value results from the child_table for parent.ID=1 look
like this:
FIELD_COLUMN VALUE_COLUMN
fieldA value1
fieldB value2
fieldB value3
And the schema configuration for fieldA and fieldB (note that fieldB is
multivalued):
<field name="fieldA" type="string" indexed="true" stored="true"
multiValued="false"/>
<field name="fieldB" type="string" indexed="true" stored="true"
multiValued="true" />
After running full-import, the document for parent 1 looks like this:
{"id":1,
"fieldA":"value1",
"fieldB":["value2"]}
But, I need (and was expecting) it to look like this instead (fieldB should
have multiple values):
{"id":1,
"fieldA":"value1",
"fieldB":["value2","value3"]}
Any help would be greatly appreciated!! Thanks!

> Can you please verify if this issue is simply due to improper implementation,

> Also, I should note that a static reference to fieldB does handle multiple

> Example: <field name="fieldB" column="VALUE_COLUMN" clob="true" />
> It only fails when I try to set the field names dynamically.
