Please select 3 options

is stated for this question yet I can only pick 2 choices. Upon picking a third choice I get a message saying only 2 options can be checked for this question.

There was an issue with the message not being repainted correctly in older version of ETS Viewer, which was fixed a few weeks ago. Could you please update your etsviewer.jar? That should fix it.

HTH,

Hi, just want a clarification about option 3. Is "the class for which the primary key has been defined" means the XYZ.class in this annotation @IdClass(XYZ.class)?

[admin]

Not sure what you mean. This option says that ff you have a hierarchy of classes (for example, A<-B<-C) and if you have defined primary key for class B then B must be an entity. This is not correct. The explanation explains why.
