magento - Custom Mage_Sales_Model_Quote_Address_Total_Abstract calculate twice: billing&shipping address -


i intended make custom credit module can use our store's credits discount. after looking examples, added checkout step onepage checkout. , extends mage_sales_model_quote_address_total_abstract have custom collector calculate total. hard coded discount value see how works:

public function collect(mage_sales_model_quote_address $address) {         parent::collect ( $address );         //if($address->getdata('address_type')=='billing') return $this;          try {              $this->_setamount ( -10 )->_setbaseamount ( -10 );          } catch ( exception $e ) {             mage::throwexception ( $e->getmessage () );          //do nothing.             }         return $this;     }      public function fetch(mage_sales_model_quote_address $address) {         parent::fetch ( $address );         //if($address->getdata('address_type')=='billing') return $this;         $title = mage::helper ( 'sales' )->__ ( 'credittest' );         $address->addtotal ( array ('code' => $this->getcode (), 'title' => $title, 'value' => -10 ) );         return $this;     }

the section in config.xml looks this:

<sales>     <quote>         <totals>             <credittest>                  <class>sales/quote_address_total_credit</class>                  <after>tax_subtotal,subtotal,freeshipping</after>                  <before>grand_total</before>             </credittest>         </totals>     </quote> </sales>

however result comes out -20 deducted. after debug tracing, custom collector called twice, once address type "billing" , "shipping". added commented code above calculate when shipping address comes in. i'm not sure if right way go.

why other class in mage_sales_model_quote_address won't calculate twice? invoked twice according tracing. , what's right way solve issue?

thank in advance.

take @ magento add fee or discount order totals
