This is probably the best place... welcome! On 25 Aug 2011 at 2:15, Barry Woods wrote: > We recently initiated amove to the SQL object store so we can get > multi-user operating.

I more or less took over from him and have been extending it for the last year or so. Having said this - a lot of the SQL OS is a bit black-box to me - I've worked on the bits that I've wanted to extend, and taken for granted that the rest works! I can fully believe that what you describe happens as you describe it - I'm not aware of there being any logic in place to halt the automatic introspection. > This same structureworks fine using the XML persistor.

I have to rely on input from Dan or Robert to understand what is happening in the XML OS vs the SQL OS. > I really don't understand this part of the frameworksufficiently to > debug this.

I should have some time tomorrow night (and following) to try and reproduce your problem and see what I can come up with. My immediate suggestion is to consider a bit of jiggery: can you make your class implement an (empty) interface, and have your collection be a collection of the interface instead of the full class? This ought to prevent the infinite recursion, but I'm not sure what else it'll break. In the mean time, maybe someone else (Rob? Dan?) can provide some hints. Regards, Kevin
