SolrParams to and from NamedList

[Peter Kirk <pk...@alpha-solutions.dk>]

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 fails if one of the parameters is an array. This could be a couple of configuration parameters like
<str name="facet.field">category</str>
<str name="facet.field">author</str>


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

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

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


How can I generate the correct conversion?

Thanks.

Hi - I think there is a bug in the conversion methods for SolrParams. But it seems that using ModifiableSolrParams (to add and remove parameters and values, which is what I want to do), is the way to go.
