I just installed SOLR-75 patch and the "schema browser" is able to view the schema perfectly. When I used the default schema with SOLR, everything is fine, but when I replace my schema ... it's throws this NullPointerException ....
One thing to note is that the "schema browser" as currently in SOLR-75 just transforms the xml file -- it does not represent any of the actual parsing of the configuration by Solr upon startup, and so would not be able to catch any errors Solr might encounter in the schema. -Greg
