xml - Modifying Magento frontend tabs to custom view : For bundled products -

i want show additional details of sub products in case of bundled products.

so did below thing add additional detail in bundled products. have used below xml code in admin "custom layout update"

<catalog_product_view>  <block type="catalog/product_view_tabs" name="product.info.tabs" as="info_tabs" template="catalog/product/view/tabs.phtml">     <action method="addtab" translate="title" module="catalog">         <alias>description</alias>         <title>description</title>         <block>catalog/product_view_description</block>         <template>catalog/product/view/description.phtml</template>     </action>     <action method="addtab" translate="title" module="catalog">         <alias>additional</alias>         <title>additional</title>         <block>core/template</block>         <template>mourtabs/bundledtabs.phtml</template>     </action>     <action method="addtab" translate="title" module="tag">             <alias>tags</alias>             <title>tags</title>             <block>tag/product_list</block>             <template>tag/list.phtml</template>         </action>         <action method="addtab" translate="title" module="catalog">             <alias>review</alias>             <title>reviews</title>             <block>review/product_view_list</block>             <template>review/product/view/list.phtml</template>         </action>  </block> </catalog_product_view> 

but can not see changes.

but when remove "catalog_product_view" above code i.e using below code:

<block type="catalog/product_view_tabs" name="product.info.tabs" as="info_tabs" template="catalog/product/view/tabs.phtml">     <action method="addtab" translate="title" module="catalog">         <alias>description</alias>         <title>description</title>         <block>catalog/product_view_description</block>         <template>catalog/product/view/description.phtml</template>     </action>     <action method="addtab" translate="title" module="catalog">         <alias>additional</alias>         <title>additional</title>         <block>core/template</block>         <template>mourtabs/bundledtabs.phtml</template>     </action>     <action method="addtab" translate="title" module="tag">             <alias>tags</alias>             <title>tags</title>             <block>tag/product_list</block>             <template>tag/list.phtml</template>         </action>         <action method="addtab" translate="title" module="catalog">             <alias>review</alias>             <title>reviews</title>             <block>review/product_view_list</block>             <template>review/product/view/list.phtml</template>         </action> </block> 

i able see "additional" details in magento frontend tabs, on product listing page see below fatal error:

call member function getid() on non-object in   d:\wamp\www\myfolder\app\code\core\mage\review\block\product\view\list.php on line 40
