Hello, The spec seems to say that <jsp:setProperty /> will try to set any property (in addition to the types in table 4.1) from a string in the value attribute or request parameter if a PropertyEditor with a setAsText() method can be found for that type. I've tested a bean and property editor and they work ok when building an applet with an IDE, but I get a NullPointerException when I try to use them in a JSP page in JRun. 1) should the setProperty tag work for any custom type that can be represented as a string and has an editor? 2) does each vendor implement their own version of the useBean and other standard library tags?
