Error adding maps

Hi to all!
Sorry for my bad English.

After installation, when I try to add a card, I see a error:

( ! ) Strict standards: Declaration of ZhGoogleMapTableZhGoogleMap::_getAssetParentId() should be compatible with JTable::_getAssetParentId($table = NULL, $id = NULL) in C:\wamp\www\life.com\administrator\components\com_zhgooglemap\tables\zhgooglemap.php on line 88

Please help fix a error!
Joomla 3.0.3
zhgooglemap.php

You can remove E_STRICT from php.ihi file, restart Apache and you will not see it.

As for component - I'll think of this methods, may by will do some changes later
