I tried to reproduce the issue, using the presented code, but to no avail. I have attached my test project so that you can compare it with yours and check if there are differences in the setup. You can find also a screen capture
, demonstrating the behavior on my end.
The encountered error is most probably caused by an Ajaxified control on your page, but given the attached code snippet I am not able to provide more information on the matter. Please open a standard support ticket
and try to modify my test project so that the issue is reproducible and send it back. If you aren't able to do so, you can also send a sample, runnable project that isolates the problem
so that we are able to inspect it locally and suggest a solution.
