[eclipselink-users] Fetchgroup usage / unfetched basic attributes

["Hahn, Markus" <Markus.Hahn@xxxxxxxxxxxxx>]

Hi folks,

we use the EL Fetchgroup features and encounter some behaviour we cant explain.

In many cases, EL works as expected concerning the basic mappings (String, Long….): the attributes are fetched if they are not mapped as “fetch=LAZY”, independently of using a Fetchgroup on the query. Basic mappings don’t have to be included in the Fetchgroup.

In some cases, this does not work: the basic attributes are NOT loaded. If we add them to our Fetchgroup, they are loaded.

Is it a bug? Does anybody has a hint how to solve this problem?

Best Regards, Markus
