Ok. Maybe it's my fault don't explain very well the problem. I try
again ... the last. Forget $_POST. Find here another example:
Page1.php
<?php
session_start();
$_test = array('one'=> 'first','two' => 'second',
'last'=>'last');
$_SESSION = $_test;
echo "<pre>";
print_r($_test);
print_r($_SESSION);
echo "<a href='page2.php'>to page 2</a>";
?>
page2.php
<?php
session_start();
echo "<pre>";
print_r($_SESSION);
?>
$_SESSION in page2.php is empty. It's no good.
try now another one.
Page1_a.php
<?php
session_start();
$_test = array('one_a'=> 'first','two_a' => 'second',
'last_a'=>'last');
foreach($_test as $key => $value) {
$_SESSION[$key] = $value;
}
echo "<pre>";
print_r($_test);
print_r($_SESSION);
echo "<a href='page2.php'>to page 2</a>";
?>
now $_SESSION is correctly full.
I repeate once again... before rel. 5.0.4 never happen this
problem.
Nothing to do with POST, isset() or empty(). Only it was the more
lighting problem for me.
Thnx for the attention and best regard.

Read carefully my last comment.
Change isset() to !empty() and see that it works perfectly.

ref.
$_POST is always set, it's just empty when there is no POST data.
So it comes that you set _SESSION to empty array().
No bug here -> bogus.
Problem is not POST of course is empty after refresh page. Problem is
"NO DATA had stored in session save file".
you can try also:
if(isset($_POST) && !empty ($_POST)) {
Php 5.0.3 and previoulsy are true.
Thanx any way...

Sorry, but I see a refresh link error in page2.php
Last line is href = "page2.php" and not href=bug2.php....
page2.php <-- correct version, thanx.
<?php
session_start();
if(isset($_POST)) {
$_SESSION = $_POST; }
else {
$_POST = $_SESSION; }
echo "<pre>";
print_r($_POST);
print_r($_SESSION);
echo "<a href='page2.php'>refresh</a></pre>";
?>
After page refresh $_SESSION is empty and any session data stored in
session save file.

No errors or notices are displayed.
Im sorry, but right now, I don't have any available URL at this time.
Here you find all reproduced bug code:
pag1.php
<?php
$html = <<<EOD
<html><body><form action = "page2.php" method = "post">
name <input type="text" name="nick" value="pippo"><br />
city <input type="text" name="city" value ="Turin"><br />
<input type="submit" name="submit" value = "submit">
</form></body></html>
EOD;
echo $html;
?>
page2.php
<?php
session_start();
if(isset($_POST)) {
$_SESSION = $_POST; }
else {
$_POST = $_SESSION; }
echo "<pre>";
print_r($_POST);
print_r($_SESSION);
echo "<a href='bug2.php'>refresh</a>";
?>
