Undefined index after upgrading to PHP 5

[mrdance]

I have a simple form with a textarea named "message". When loading the page I use the following syntax:

if (!isset($_REQUEST['message'])) {
// show form
} else {
// show result of form
}

But the "else" case never happens?!! All this after upgrading to 5 from some 4.x version.

Any ideas??

It works as it should (skips to "else" when submitted) for me on both versions. I used this code to test:

if (!isset($_REQUEST['message'])) { 
    echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';
    echo '<input type="text" name="message" />';
    echo '<input type="submit" value="Submit" />';
    echo '</form>';
} else { 
    echo $_REQUEST['message'];
}
