Hi,

I have 2 single table hierarchies :
- B1 inherits from B
- A1 inherits from A (abstract), A1 has a to-many relationship to B, let's call it toBs

is it possible to prefetch this relationship ?

We can't manage to get it work, I'll paste the obscure exception tomorrow but can anyone confirm that this kind of prefetch works with EOF ?

I am not sure, I will take a look at the trace.


I've also tried ERXBatchFetchUtilities which seems promising "This works much like prefetching with fetch specifications, however this implementation is able to work around inheritance where prefetching fail", but no luck :/

How did that fail?

Chuck
