On startup of a Maven-based web app there is verbose logging of object checking whether enhancement has been applied to a wide range of classes, many of which have nothing to do with the entity layer. For example, it is checking whether PrimeFaces JSF toolkit classes are enhanced. I am using

Hi, Today I was playing with some date- range queries in explorer and found a small problem. When you try to use queries like this: SELECT o from TestObject o where o.date :someDate where o.date is java.util.Date, 'where' doesn't work as it should. Results are not filtered by date

I have a "Table" that currently has  @Id private String userId; @Id private long range ; private String someOtherField; I need to add a @Id to someOtherField.  But when I add that, and query the table all the PK fields are null or 0.  What can I do to modify primary keys?
