weird behaviour
0

Hi,

I have a test project (for DO 4.4) derived from the WcfSample. Download here: WCF-Test.zip

When running the client I get a NullRef-Exception in WcfSample.ConsoleService.OrderingService.GetThings() (in OrderingService.cs).

It can be solved either by changing InheritanceSchema of WcfSample.Model.ThingDetail (in Model.cs) from ClassTable to ConcreteTable or by commenting out the class-definitions of ThingDetailA and ThingDetailB (in Model.cs) (which aren't used in any way, btw.). Which leads me to believe that either I'm doing something horribly wrong or there's a bug in DO somewhere.

Best Regards, Sebastian

UPDATE:

I've investigated the issue and discovered that you are using Prefetch API. In DataObjects.Net 4.4 Beta 1 it does not function properly.

Beta 2 will contain the updated and fixed version of Prefetch API.

Thanks, Dmitri. Do you have an ETA on Beta 2?

I suppose, it will be the beginning of the next week.

Sorry, my prognosis was wrong, Beta 2 is still in work.

DataObjects.Net 4.3.7 & 4.4 beta 2 is released
