Hi Thomas These are probably going to be "dumb" questions but I cannot find answers anywhere. [The mail list archive is so frustrating to use.]
1. How do I lock 'b' elements from a collection using the ODMG API? 2. Can I double check regarding the collection-descriptor auto-retrieve/update/delete that in the Advanced O/R is states: "These default settings are mandatory for proper operation of the ODMG and JDO implementation." that this means accept the defaults when using ODMG? (I get errors when I set auto-update="true", but when using deletePersistent(obj) I found setting auto-delete="true" removed the 'b' elements but when not set the 'b' elements remained persisted. 3. As DList is abstract what would I use in a model object to store 'b' elements? I see where the Implementation object can create a new DList odmg.newDList() ????

If you were using DList as your collection class this won't be required. cheers, thomas Saman Ghodsian wrote: > Hi there, > > Here is the situation......
