Issue with string composite id

[jypelle]

type FavoritePlaylistId struct {
    UserId     string
    PlaylistId string
}

type FavoritePlaylistEntity struct {
    Id         FavoritePlaylistId           `storm:"id"`
    UpdateTs   int64                        `storm:"index"`
    UserId     string                       `storm:"index"`
    PlaylistId string                       `storm:"index"`
}

Steps to reproduce:

• Open Storm Db
• Save one FavoritePlaylistEntity
• Retrieve FavoritePlaylistEntity From Id ->Succed
• Retrieve FavoritePlaylistEntity From UserId (index) ->Succed
• Retrieve FavoritePlaylistEntity From PlaylistId (index) ->Succed
• Retrieve FavoritePlaylistEntity From UserId & PlaylistId ->Succeed
• Close Storm Db
• Open Storm Db
• Retrieve FavoritePlaylistEntity From Id ->Not found!
• Retrieve FavoritePlaylistEntity From UserId (index) ->Not found!
• Retrieve FavoritePlaylistEntity From PlaylistId (index) ->Not found!
• Retrieve FavoritePlaylistEntity From UserId & PlaylistId ->Not found!
• Retrieve All FavoritePlaylistEntity ->Succeed

I think there is a pb when you close and reopen the database. Don't know if it's a bbolt issue or a storm issue.

Found a workaround replacing:

Id         FavoritePlaylistId           `storm:"id"`

With

Id         string           `storm:"id"`

And calculate Id with concatenation (Id= UserId+':'+PlaylistId)
