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>();
