Another option would be to check out Solr 1.4.1 source code, fix the issue and recompile the clustering component. The quick and dirty way would be to convert all identifiers to strings in the clustering component, before the they are returned for serialization (I can send you a patch that does this). The proper way would be to fix the root cause of the problem, but I'd need to dig deeper into the code to find this. Staszek
