session parm in config.php

I have a problem configuring session in yii. Appreciate any help!

As soon as I added a session parm to config/main.php like below, I get a PHP Error,

"Invalid argument supplied for foreach()".

	'components'=>array(


                   .....





		// Session


		'session' =>array(


			'autoStart' => true,


		),


             ),

/var/www/yii-1.1.8.r3324/framework/collections/CMap.php(277)

265 * will overwrite the former (different from array_merge_recursive).

266 * Recursive merging will be conducted if both arrays have an element of array

267 * type and are having the same key.

268 * For integer-keyed elements, the elements from the latter array will

269 * be appended to the former array.

270 * @param array $a array to be merged to

271 * @param array $b array to be merged from

272 * @return array the merged array (the original arrays are not changed.)

273 * @see mergeWith

274 */

275 public static function mergeArray($a,$B)

276 {

277 foreach($b as $k=>$v)

278 {

279 if(is_integer($k))

280 isset($a[$k]) ? $a[]=$v : $a[$k]=$v;

281 else if(is_array($v) && isset($a[$k]) && is_array($a[$k]))

282 $a[$k]=self::mergeArray($a[$k],$v);

283 else

284 $a[$k]=$v;

285 }

286 return $a;

287 }

In "Yii-powered Applications" ?

Seriously…
