http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21514 html:form focus function could be more powerfull Summary: html:form focus function could be more powerfull Product: Struts Version: 1.1 Final Platform: All OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Custom Tags AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] tag Form can generate dynamically javascript to put focus on a field element. This function is excellent for the first page access. But, in my web application, when a form is submit, many controls are made and we try to return specific errors for each element to give best help to our clients. For this, we use Errors tags to explain each error under each element. Good but not enough. We would like to give focus on a field specificaly related with error. This function is not implemented in the taglib HTML or it's simple, don't affect functions already present and give more power to the dynamic focus. Our solution : We implement ErrorsTag to add a new property with the same function as focus property in FormTag. Implementation ErrorsTag : When we find a correspondant error, value of this new property is set in the pageContext, in request scope. When this is done one time, this value isn't change if other errors are sent. So, we have in memory the first field associated with the first error found and defining it. FormTag : in doEndTag(), focusField value is tested. If exists, it have priority on focus form property. So we affect this new value to focus property. That all for focus We can go further and add an anchor to this error and scroll automatically to this anchor before giving focus to the field associated. It work fine, give a better result and more power to the focus property. As it's optionnal, there's no problem if someone is not interested ... but I'm sure many programmers using forms need that ! This is not really a bug but I don't know anywhere else to submit.
