Validation error displayed on custom experience dialog incorrectly

Asher: 5 days ago

In an SXA site I have cloned link list with item, and added a link custom editor button to allow editing of the list item fields. These fields have required validation. But I find that when I add values to each of those fields in the experience editor dialog and click ok I get this error:

On each of the required fields I have set it: enter image description here

If I click ok. And then go in to edit the item again then it's all green.

My template looks like this:

Why is it ignoring the field values when validating?

I had a similar issue on a Sitecore 8.2 Update 7 instance. It is a known issue in Sitecore and they provided me a Sitecore Patch.

The Sitecore patch number is SC Patch 221650-1. The patch contains a dll, which is the Sitecore.Kernel.dll. You just need to replace the one that you have in the patch.

You can contact the Sitecore Support ( and provide them the details of the error and also you can tell them that the reference number of the issue is 221523
