    Hi, All,


           I few weeks ago, I started a thread here about the needed of Cayenne POJO Objects. Maybe I'm totally wrong, but I think when Cayenne could deal with the attach/dettach POJO's objects in the DataContext automatically, we will could has less doubts like that.

            I wait paciently for this feature :-)

           Thanks and Sorry for my intrusion.

    For what its worth, I think it's a lot easier to just make a duplicate
version of the DataObject that isn't inherited from CayenneDataObject. Then
you can just use BeanUtils to load the properties in the Cayenne DataObject.
This is a little repetitive, but you can make a script to generate your
initial set automatically and then modify them to suit your needs. We do
this because it makes form validation, etc a little more convenient and is
more conducive to distributing the application down the road, where the web
app and the business logic might not necessarily be on the same server. Try
using a DataObject then :)

Thanks for your feedback Mike, that makes sense!

How about using another DataObject that hasn't been 
registered with the context to collect the data and then copy 
that data over to a live DataObject. All in one fetch, 
update, commit cycle like you suggested.

For new objects I guess I don't need a separate object. When 
it's filled out I'll only need to register it with the 
context and submit it.
