RemoteIncrementalFaultList and object ids

[Aristedes Maniatis <ar...@ish.com.au>]

The JavaDoc for the class RemoteIncrementalFaultList reads in part:

"A list that serves as a container of Persistent objects. It is  
usually returned by an ObjectContext when a paginated query is  
performed. During creation, only the first "page" of objects is fully  
resolved; for the rest of the objects only their ObjectIds are read."


In our case we have a paginated list fetched in 3 tier on a client.  
We want to be able to find a particular record in this list and we  
know its primary key (ObjectId ?). But we don't want to have to  
resolve the entire list to do so.

There appears to be no field in RemoteIncrementalFaultList which  
stores the ObjectId and I can't find anything in the source code  
which suggests it is accessible. What I really want is:

getObjectId (int index) -> objectID

or

indexOf (objectId) -> index


But I wonder if the JavaDocs are correct and such a thing is possible  
at all. It appears that RemoteIncrementalFaultList resolves faulted  
records purely by index in the list and not by ObjectId.

Ari,

Your suspicion is right. ObjectIds are not being transfered to the  
client to make it more efficient. RemoteIncrementalFaultList evolved  
a bit since the javadocs where written - I'll need to update the docs.

P.S. you don't seem to be subscribed to the list with this address (I  
got your message in the moderation queue), so you will not receive  
the replies that are sent directly to the list.
