mongoTemplate update by ID not work?

[leewill]

I'm using Spring Mongo 1.0.0M2. I tried to update a property in a document and it failed when query by ID. This is the mongo template configuration:

@Override
public Mongo mongo() throws Exception {
	ServerAddress address = new ServerAddress( "127.0.0.1" , 27017);
		
	MongoOptions options = new MongoOptions();
	options.autoConnectRetry = true;
	options.connectionsPerHost=10;
	options.threadsAllowedToBlockForConnectionMultiplier=5;
	options.maxWaitTime=6000;
	options.connectTimeout=0;
	options.socketTimeout=0;
		
	Mongo mongo = new Mongo(address, options);
	return mongo;
}

@Override
public MongoTemplate mongoTemplate() throws Exception {
	MongoTemplate mongoTemplate = new MongoTemplate(mongo(), "ecl");
        mongoTemplate.setMongoConverter(mappingMongoConverter());
	mongoTemplate.setUsername(USERNAME);
	mongoTemplate.setPassword(PASSWORD);
	return mongoTemplate;
}
	
//	public String getMappingBasePackage() { 
//	    return "dist.bo";
//	}

The injected MongoOperations works for save document, update entire document. It also works fine when:

mongoTemplate.updateFirst("entityCollectionName", 
        query(where("name").is("object name")), 
	update("deleted", true));

but never work if the query is

        query(whereId().is(the_document_id)),

The funny thing is, retrieving document by id with such query works fine:

mongoTemplate.findOne(query(whereId().is(the_document_id)), 
	MyDoc.class);

I never found any tutorial/reference talking about update a property by query ID.

Did I miss something?

it turned out not just me who got this problem:

solved the problem. You can't use whereId().is(....). Here's my test codes:

Query q = query(whereId().is(new ObjectId(entity.getId())));
logger.info("query: " + q.getQueryObject());
		
WriteResult result = mongoTemplate.updateFirst(entityCollectionName, 
	q,
	update("deleted", true));

This one will fail, and the query string in "q" is:
{ "id" : { "$oid" : "4db0718de0f46a0e2828532d"}}

But if change the whereId() to where("_id"), i.e.,

Query q = query(where("_id").is(new ObjectId(entity.getId())));

It works, and the query string in "q" is:
{ "_id" : { "$oid" : "4db0718de0f46a0e2828532d"}}

It seems whereId() in update has some issue, as it works perfect in save(), find()
