Validation Rules and $originalfeature

[James_Blouin]

Hi all. I'm attempting to write a Validation Rule that checks if the feature's geometry has changed using the $originalfeature global. I'm getting an error message when saving the rule that states that:

"The attribute rule expression contains $originalfeature, which is only valid with the update trigger for constraint and immediate calculation rules."

Has anyone encountered this as well? I'm a bit confused since the $originalfeature variable appears in the Attribute Rule Validation profile: Attribute Rule Validation | ArcGIS Arcade | ArcGIS Developers

Hey James,

we will have to fix that page in the doc, the Validation rules and batch calculation rules execute on demand via the evaluate call and not on user edits. 

So $originalFeature isn't applicable. 

If you think about it the edit has already been made, running evaluate we have no idea what happened to the feature

Thank you for the explanation, Hussein! That makes sense to me now that you mentioned that the edit has already been made before hitting the Evaluate button.
