If I am put my 5 cents (inflation). My personal default is (PERSIST, MERGE, REFRESH) and in the circumstance that I need to put a DELETE then I would if necessary. I assume beginner Seam developers would absolutely freak if they saw a detached entity exceptions when they first use Seam's reveng.<br>

2) What default do you think we should use for reveng, ALL or NONE (or something else ?)<br>

<br>With none, you have to go through and do persists all over the place...and in a real application, that top level object typically has 10+ relationships, esp if lookup tables are used.<br><br>-Dan<br> </div></div><br>
