Description
When updating a existing resource with a JSON PUT with this sample code
@Document public class Ticket { @Id private String id; @Version private Long version; private String type; private Map<String, String> texts; }
and JSON
{
"version" : 1,
"type" : "HR",
"texts" : {
"description" : "Let's test1234"
}
}
I get the following stack trace:

The reason seems to be that in DomainObjectReader the PersistentEntity for a HashMap is null.
public class DomainObjectReader { public <T> T readPut(final ObjectNode source, T target, final ObjectMapper mapper) { Assert.notNull(source, "ObjectNode must not be null!"); Assert.notNull(target, "Existing object instance must not be null!"); Assert.notNull(mapper, "ObjectMapper must not be null!"); final PersistentEntity<?, ?> entity = entities.getPersistentEntity(target.getClass());
This works before DATAREST-461 was included.
You can find a example, to reproduce here https://github.com/sebastian-sch/mongo_data_rest
