Modify problem after update to v1.1.7

[druidproject]

FindAll works fine, but when I'm trying to modify data in collection, it wrotes to me ok, "26 rows may be affected", but at the same time, I found that data hasn't change. It's started when I've updated to last version of RockMongo v1.1.7 and MondoDB v2.6.3.

And when I'm trying to update single document, have another problem.
"Only valid json is accepted"
But if I change field with NumberLong or NumberInt, it's works!
"creation_date": NumberLong(1399561719) to "creation_date": 1399561719

Please, fix that problems!
