http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22700 Setting focus to a form field that doesn't exist causes javascript error on loading the page Summary: Setting focus to a form field that doesn't exist causes javascript error on loading the page Product: Struts Version: 1.1 Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Custom Tags AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] After processing the <html:form> tag, some javascript is displayed to force the focus to one of the components in the form. However, it is possible that the form field may not exist or may become a label if a user doesn't have modify access to the field. In this case a javacript error of 'Object Not Found' is displayed in a dialog box when the page is loaded. The existing javascript focuses into the form field provided the field isn't hidden. However, an additional check should be performed to ensure that the form field exists. Only then (in addition to the field not being hidden) should the javascript move the focus to the field. Resolution ---------- In the FormTag's doEndTag() method a call is made to renderFocusJavascript(). The renderFocusJavascript() method does the following: results.append(" if (focusControl.type != \"hidden\") {"); Change this to: // Was previously setting the focus to the first text component // if it wasn't a hidden field. // Add an extra check to verify that the field exists. results.append(" if (! focusControl.type === undefined && "); results.append(" focusControl.type != \"hidden\") {"); --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
