Mark S updated SOLR-4422: ------------------------- Description: The SolrJ DocumentObjectBinder class does not retain order when reading in dynamic field values into a Map. More specifically, the order in which the Map is populated by an application is different to the order in which the Map is repopulated by SolrJ. ---- @Field("dynamic_field_values*") private Map<String, Object> dynamicFieldValuesMap = new LinkedHashMap<String, Object>(16); ---- I believe the following would address this issue. - allValuesMap = new HashMap<String, Object>(); + allValuesMap = new LinkedHashMap<String, Object>(); Or, maybe the DocumentObjectBinder should directly populate the Map field directly if that field is not null. ---------------- I am pretty sure issue does NOT exist with dynamic field values in a List, as the SolrJ DocumentObjectBinder uses a List implementation that retains ordering "new ArrayList();". So the following will retain ordering. @Field("dynamic_field_values_ss") private List<String> dynamicFieldValues = new ArrayList<String>(); was: The SolrJ DocumentObjectBinder class does not retain order when reading in dynamic field values into a Map.
