NullPointerException by getting map with null values

[phimi]

Hi all,

i've a map in my collection that looks like this: 

"someMap" : {

"de" : null,

"en" : null

}

When I try to get this with morphia than the following error is thrown:

java.lang.RuntimeException: java.lang.RuntimeException: java.lang.NullPointerException

at com.github.jmkgreen.morphia.mapping.DefaultMapper.fromDb(DefaultMapper.java:531)

at com.github.jmkgreen.morphia.query.MorphiaIterator.next(MorphiaIterator.java:46)

at com.github.jmkgreen.morphia.query.QueryImpl.asList(QueryImpl.java:261)

...

This map was added with morphia. So I think it must be possible to get them back on this way. Is this a bug in morphia? Has anybody an workaround for this?

Regards
