Subject Re: Commit with validation errors in detail table
Date Wed, 07 May 2008 07:12:03 GMT
Hi Julien,

Yes, DataContext commit is all or nothing. One possible way to go  
about it is to catch the ValidationException, iterate through the list  
of failures collecting source objects of all failures. Then do  
DataContext.invalidateObjects(failed) and retry the commit.
