[Typo3-dev] Save objects in Session

[Rui Santos]

Hi, i'm doing an extension and in function main(..) of class 
tx_ControlPanel_pi1 i'm doing this: 


...
$i=&$GLOBALS["TSFE"]->fe_user->getKey("ses","i");
if(!isset($i))
{
 $i= new I();
 echo "hi";
}
... 

with debug(array($GLOBALS["TSFE"]->fe_user->sesData['i'])) i check that an 
instance of I() is saved in session, but my problem is everytime i do a 
refresh (but not close the browser) the key "i" in session gone, and enter 
in if(!isset($i)).
I would like to save the object I() once in session until the client close 
the browser.
What i'm doing wrong?
(If this list isn't the best one to resolve my problem, can any tell what 
are? ) 

Thanks any help. 

Rui
