Hi All!
I just wanted to reuse this post since I have quite similar problem ant it could not be solved with the proposed approaches :-/
I am using SS V 3.1.13.

I have a simple DataObject that has a Varchar field "name". This attribute should be used only once (is unique) across the system.
I have used AjaxUniqueTextField but this construct is not working properly :-/ If saving an existing alraedy persisted DO it says the "name" is not unique (but it does!). In the AjaxUniqueTextField there is one important Thing missing - exclusion of all entries with ID of the current Instance if already persisted.

I tried to implement the proper validation in an inherited Class of RequiredFieldsValidator, but unfortunately I need the ID of the Record being validated, to build correct DB Query - but I can't find it in the $_REQUEST var anymore like in the previous answers.

Is there any other Pattern to implement Unique Value Validation?
Or how can I access the DO ID in the Validator?

Thanks in advance!

just insert

   public function getValidator() {
                  
                  // Answers a validator for the record.
                  
                     return new RequiredFields('SystemName','Name');
                  
                  }

in your dataobject
