Hi,
This isn't really a Struts issue per se, it's a frames issue.
When you set the target of the form to display, the response from the
server is going to go into the bottom frame, regardless of what the
outcome is (i.e., whether there are errors or not). This is just how
frames work.
You can do what you want, but it will require client-side coding.
I would suggest having a third frame with a size of 0 (making it hidden)
and direct your response to it. Add some Javascript to the page that is
returned that fires in response to the onLoad event. If errors came back,
copy them over to the search frame, otherwise copy the whole page to
display. Let's assume you call the hidden frame "hiddenFrame", and let's
assume there is a <div> with an ID of "errorDiv" in both the returned page
and what's in the search frame... Here's what I would do:
<html>
<head>
<script>
function loadHandler() {
if (errorDiv.innerHTML != '') {
window.top.search.errorDiv.innerHTML =
window.top.hiddenFrame.errorDiv.innerTML;
} else {
window.top.display.document.open();
window.top.display.document.write(
window.top.hiddenFrame.document.documentElement.outerHTML);
window.top.display.document.close();
}
</script>
</head>
<body onLoad="loadHandler();">
...
</body></html>
So, if errors are present in the <div> on the returned page, they will be
copied over to the <div> in the search frame. If the <div> is empty on
the returned page, meaning no errors occurred, the entire page is copied
over to the display frame.
I'm not sure this is 100% cross-browser, you probably need to use
getElementById() to make it so, but the basic theory works (I know because
I do this in a prod app I have).
