go to post Ariel Glikman · Jun 27, 2023 Hi Gautam, As it stands your class is not an object class (https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...). In order to instantiate an object, make sure the class inherits from %RegisteredObject or a subclass of it. We do this in ObjectScript as follows: Class Sample.Header Extends %RegisteredObject { /// your code }
