MappingMongoConverter could not read the org.joda.money fields back from MongoDB

[krishmn]

I was using 1.0.0.M4 and having a pojo with a field called unitPrice mapped to org.joda.money.Money type.

I was able to save the data successfully, but while retrieving the same pojo spring throws the following exception.
Appreciated your help in this regard.

Using the following joda money jar -- org.joda.money 0.6

I've resolved this by adding custom read/write converters for CurrencyUnit and hooking into MongoMappingConverter.
