Well, the process hasn't gotten to any level of detail. I expect that the EG will take what the major JPA implementations have done and standardize the functionality. Or they will take an abstraction like Patrick is talking about to produce a JPAQL string. There are advantages and disadvantages to both techniques. I think the best thing for us is to discuss on this list and then try to influence the standard. Craig > > On 7/16/07, Patrick Linskey <[EMAIL PROTECTED]> wrote: >> Hi, >> >> Keep an eye open here...
