[hibernate-dev] [OGM] Id generation strategies

Hi, I'm rather confused by the way how OgmIdentityGenerator, OgmSequenceGenerator and OgmTableGenerator interact. Basically, the first two just delegate to the latter. Now intuitively I'd have expected an exception when explicitly using a generation type not supported on a given datastore, say @GeneratedValue(strategy = GenerationType.SEQUENCE) on MongoDB. But as we always delegate to the table strategy, such exception is not raised. Also several attributes of generator annotations are ignored; E.g. naturally(a)SequenceGenerator.sequenceName(), but also @TableGenerator.valueColumnName. What has been the motivation behind this design? I guess a change to GridDialect may be required for making explicit which strategies are supported on a given backend. Thanks, --Gunnar
