 Description  « Hide
When the user performs an SQL query and specifies the result class as a persistable class, we currently detect if they have selected the version and datastore id columns (for later usage). We should also do the same for any discriminator column.

SVN trunk adds support for this, but you have to ask the question if wanting instances of a persistable class why not use JDOQL/JPQL?
