There were issues with the use, with Silverlight, of the NumericIdGenerator sample in the Learning Resources. We've updated that sample, which is now used in the _DocumentSnippets solution associated with the Object Persistence chapter.

If you call GenerateId() on an EntityManager, it must have access to a valid implementation of DevForce's IIdGenerator interface. You can find samples of that in the Learning Resources in the following folder:

     Learning Resources\040_BusObjPersistence\AddingDeleting\Snippets\NumericIdGenerator

The class that implements IIdGenerator must be included in an assembly that is listed as a DevForce probe assembly. An easy way to satisfy that requirement is to include it in the assembly that contains your domain model.

You may also wish to read the material in the Object Persistence chapter on "Generating Unique Identifiers". The section on "ID Fixup", in particular, contains from information about using an IIdGenerator implementation.

Hi,

I have problem to save the record,i am getting error as per the attachment
kindly help me.
the exception message is
"Save failed - IdGenerator problem - unable to convert all temp ids to permanent ids/nThis may be caused by the server not being able to locate an IIdGenerator instance via probing/nor it can be caused by not providing a corresponding real id for each temp id in the GetRealIdMap/nmethod of your IIdGenerator implementation."

Thank you
