Could you give us a bit more information? How are you getting this information into Solr? SolrJ? DataImportHandler? It's hard to see where the null value is getting dropped, if we don't know the path that it is coming in.
I suspect that the default attribute won't do it. It's possible that you might be able to do something with an UpdateRequestProcessor. But I'm afraid the null values may be gone by that point. If I knew how you were getting the data in, it would be easier to check.
