Hey guys,

I'm having this exact same problem.  Was there ever a solution to this?

To answer the questions asked earlier on:

>>>> 1. What is the type of the primary key? If it is a primitive,  
>>>> and you change it to be a wrapper type (e.g., java.util.Long  
>>>> instead of long), does it change anything?

I originally had my pk as an int, but changed it to java.util.Integer, but
it did not doing anything

>>>> 2. Does this happen for all key values you have tried, or is  
>>>> there a specific one for which it fails? Specifically, I am

My problem occurs regardless of the primary key value

>>>> 3. Is the instance being serialized/deserialized before it is  
>>>> getting merged?

It does.  I am using a client/server webapp

>>>> 4. If you enable SQL logging, do you see any lookups being

Any tips on how to enable the SQL logging?  I know lookups work, but I do
not know if they work during merge()

Thank you in advance
