What is the best way to uncheck a Struts checkbox? Is there a certain option I can use from within the JSP tag to account for this? What I have been doing up until now is checking for the existence of a request parameter in my Action class, and if it does not exist then manually setting the respective property in the ActionForm (usually to false). However, this is not preferred since it presents a serious problem when the class type of the ActionForm is not known. If the instance type of the ActionForm is unknown (i.e. it is a subclass of another ActionForm), I can't very well invoke a method to set a property to false! This problem just recently presented itself since I now have a Javabean that can be an instance of multiple types, linked to one ActionForm- all handled by the same save Action. What can I do??? Hopefully there is some other way to handle this, otherwise I will be forced to write instanceOf statements to determine type and cast the ActionForm- which I consider bad design. Thanks, Bob
