Dynamics 365 CRM: Error while saving a form when Multiselect Option Set has Values selected

(0) ShareShare

Posted on by Mian Ahsan 35

Hi,

I have a CRM custom entity and on the form I have added a Multiselect Option Set. When I select a value in Multiselect option set and save I get following error.

Multiselect has 2 simple values Option 1, Option 2.

    We are having the same problem. It worked for a while then stopped for no apparent reason.

    I got fixed somehow, for months, and now same issue again. No changes.

    Very strange and annoying ;) We cannot simply recreate the field every time.

    Thanks for your reply, Efrain.

    It is Microsoft Dynamics 365 Version 1612 (9.0.17.8) (DB 9.0.17.8) on-premises.

    There is custom code on the form but none which has any impact on the Multiselect Option Set.

    No, I have not tried anything like fiddler.

    Infact this worked previously on the same form, but then I have to delete the field and recreate it. Since then I am facing this issue.

    Have you tried looking at the request using something like Fiddler or used Dev tools?  If so, did you notice anything with the format of the request? Do you have any custom code on the form?  What build of D365 is this?
