Description

Setting multiple values to a multivalued field via an XML atomic update request is resulting in what appears to be the output of a toString() method. See the examples below.

I ran into this issue using the output for atomic updates from the fix for Solr-4133 to ClientUtils. The server being used is the base 4.0.0 release.

curl 'https://localhost/solr/update?commit=true' -H 'Content-type:text/xml' -d '
<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="set">one</field>
<field name="status" update="set">two</field>
</doc></add>'

Yields the following in Solr:

  <arr name="status"><str>{set=one}</str><str>{set=two}</str></arr>

Changing the second "set" to an "add" has the same effect.

If I only set one value though, it works correctly:

<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="set">one</field>
</doc></add>

Yields:

<arr name="status"><str>one</str></arr>

It also works fine if I split it into two operations

<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="set">one</field>
</doc></add>
<add><doc boost="1.0">
<field name="id">test</field>
<field name="status" update="add">two</field>
</doc></add>

Yields:

<arr name="status"><str>one</str><str>two</str></arr>

Oddly, it works fine as a singe request in JSON:

curl -k 'http://localhost/solr/update?commit=true' -H 'Content-type:application/json' -d '["id":"test", {"status":{"set":["one", "two"]}}]'

Yields:

<arr name="status"><str>one</str><str>two</str></arr>
