Update byte[] validation error

[Petr Šatka]

Hi Telerik.
I have a problem again. I can not update the image column DATA in my table via the RIA Services. Insert works fine, but update has the validation error "Index was outside the bounds of the array".

In Fidler log, you can see that the error was thrown by Telerik.OpenAccess.Ria.AttachChanges.FindChanges().

Thank you for your help.

Regards.
Peter

Hi Telerik.
Edit: I fixed the typo in the update code example (new byte[5]). (It has nothing to do with error in real application.)

Peter

Hi Petr Šatka,

I've found and fixed the issue. The next version will contain the fix. Unfortunately, there is currently no workaround for this issue; only null values will work.

Kind regards,

Hi, I am using 2011 Q3 version and I am having the same problem during the Update. Is there any workaround?
Tks.
