You need to check for “empty”, not “null”. For example...
$VisualCharacteristicSpecification/Sketch_Id_Id != empty
Hope this helps.
Hi, Please use the below condition to check for null!
$VisualCharacteristicSpecification/Sketch_Id_Id != empty and $VisualCharacteristicSpecification/Sketch_Id_Id != ''
Hope this helps!
You can use != empty and also for strings you can use the rule IsEmptyString , this you will get in community common module .
Also i would suggest you to go through rapid course in Learning path.
I hope you are having validation for image,
If you want to check whether that image has contents then check HasContents boolen is true or not
