server is also 7.4 and your assumption/check on null values on input doc seems legit... I have added some checks before pushing the doc to solr and replaced null values with some default values, and updates seem going through w/o problem... though having a little bit explanatory logs on server side might be useful...
thanks a lot for pointing out the null fields ----- Zeki ama calismiyor... Calissa yapar... -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
