Hi,

In a request-handler, if I run the below code, I get an exception from Solr
undefined field: "[Ljava.lang.String;@41061b68"

It appears the conversion between SolrParams and NamedList and back again f=
ails if one of the parameters is an array. This could be a couple of config=
uration parameters like
<str name=3D"facet.field">category</str>
<str name=3D"facet.field">author</str>


public void handleRequestBody(SolrQueryRequest req, SolrQueryResponse rsp) =
throws Exception {

  SolrParams params =3D req.getParams();
  NamedList parameterList =3D params.toNamedList();
  SolrParams newSolrParams =3D SolrParams.toSolrParams(parameterList);

  req.setParams(newSolrParams);
  super.handleRequestBody(req, rsp);


How can I generate the correct conversion?

Thanks.
