I have a validation rule created in Talend MDM model Entity to check for value exists in an element. This expression seems to not work as expected . As per the expression user should enter a value in an attribute but it allows empty values. This rule can also be implemented by turning the element to require 1:1 but as a requirement we have to implement this as validation rule. Please advise.
Could you please clarify in which Talend MDM version/edition you are?
