OF Arena: Attribute with default value and visible if relevant, and with validation rule reports error even when created default is correct

Dear Open Foris team, In my "ecoresto_test" survey, I have the attribute "detail" that is visible only after another attribute ("record_type") has been evaluated. The default value for the attribuet "detail" is determined by the value entered in the attribute defining "detail"'s visibility. For example, if "record_type" = "Pot" then default value for "detail" is "3". Then I have a validation rule on the attribute "detail" because, besides the proposed default, the user can only pick certain options for that attribute, within a given type of record_type selected. The problem is that even though the user has simply followed the default for "details", and therefore it is correct by definition (it cannot be wrong), Arena reports the record as an error. It seems Arena evaluates the error (validation rule) just after the attribute "detail" becomes relevant but before its default value get created, and therefore it reports it as an error. Can you assist with this issue? Best wishes, Bruno
