Assignee: Damien Raude-Morvan
> MongoStore: Document or List mapping change cause NPE in clearDirty()
> ---------------------------------------------------------------------
>
> Key: GORA-389
> URL: https://issues.apache.org/jira/browse/GORA-389
> Project: Apache Gora
> Issue Type: Bug
> Components: gora-mongodb
> Affects Versions: 0.5
> Reporter: Damien Raude-Morvan
> Assignee: Damien Raude-Morvan
> Fix For: 0.6
>
>
> I've found an issue in current implementation of MongoStore on [Document or
> List|http://gora.apache.org/current/gora-mongodb.html] mapping type handling.
> If your schema contains a field like this :
> {noformat}
> { "name": "keywords",
> "type": { "type": "array", "items": "string"},
> "default": null
> }
> {noformat}
> If you choose to latter defaults to an empty array instead of null value like
> this
> {noformat}
> { "name": "keywords",
> "type": { "type": "array", "items": "string"},
> "default": []
> }
> {noformat}
> loading old data will fail because of clearDirty method will try to also
> clear a null object.
> {code}
> persistent.clearDirty();
> {code}
> I implemented and tested a fix which always return a DirtyListWrapper or
> DirtyMapWrapper instead of previous null value.
