But another way to look at it is this: When a checkbox is unchecked, it has a value of "unchecked". Therefore, if you setRequired=true on a checkbox, it's always satisfied. In otherwords, a checkbox always has a value so setRequired=true has no effect on a checkbox.
-----Original Message----- From: Kent Tong [mailto:[EMAIL PROTECTED] Sent: Monday, January 07, 2008 2:07 AM To: users@wicket.apache.org Subject: "required" for Checkbox Hi, I observed that if "required" is set to true for a Checkbox, Wicket will ensure that the Checkbox is checked. If it is cleared by the user, it will be treated as an error. See https://issues.apache.org/jira/browse/WICKET-1221 and https://issues.apache.org/jira/browse/WICKET-1260 for some background. For me, "required" means that a value must be provided. For a check box, if it is checked, it has a value of true. if it is unchecked, it has a value of false. So it always satisfy "required". Treating "required" as "having a value of true" doesn't sound correct to me. If we consider the error message that should be used, for the case of forcing the user to check the box (eg, [x] I have read the agreement), it should say "you must check xxx", which is quite different from the error message for "required": "you must provide xxx". For the use case of forcing a checked check box, I think an CheckedValidator should be used, which can provide a much better default error message. Not that it's an important, but just to see what others think. ----- -- Kent Tong Wicket tutorials freely available at http://www.agileskills2.org/EWDW Axis2 tutorials freely available at http://www.agileskills2.org/DWSAA -- View this message in context: http://www.nabble.com/%22required%22-for-Checkbox-tp14662131p14662131.html Sent from the Wicket - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
