Warning: Attempted to call getRecord() on a DSResponse with null DataSource

[pilami]

Using SGWT 3.0 release, we get this warning often, I have read this thread below but it did not help much because we don't have access to the response.

As the stack trace shows it, our code calls
IDACall.processRPCTransaction(RPCManager, RequestContext)

And so the DSResponse is not under our control, I have looked at the request in the RPCManager and it has a DataSource.
So what can we do to get rid of this warning?

Thanks,

Gael

As the other thread indicates, you need to add a DataSource to DSResponses you generate. All automatically generated DSResponses already include DataSources. If you disagree, please show a minimal, standalone test case that allows the warning to be reproduced.

Thanks for your reply.
As I said above, the response is automatically generated by SGWT.
So, I'd be glad to provide you with a minimal test case, could you just point me to a server-side sample that I could use as a starting point?

Thanks

Make sure you are using a fully patched build (see SmartClient.com/builds), then, if the problem is still happening, pick any sample where you think you can reproduce it, and show minimal modifications to that sample that cause the problem.
