getChildHtml()方法在magento的产品列表页面(类别view.phtml/product list.phtml)中不起作用

Question

我在getToolbarHtml()之后调用list.phtml文件中新创建的引用.但它没有显示任何东西.我的catalog.xml文件类似于:

<reference name="content">
            <block type="catalog/category_view" name="category.products" template="catalog/category/view.phtml">
                <block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml">
                    <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
                        <block type="page/html_pager" name="product_list_toolbar_pager"/>

                        <!-- The following code shows how to set your own pager increments -->
                        <!--
                            <action method="setDefaultListPerPage"><limit>4</limit></action>
                            <action method="setDefaultGridPerPage"><limit>9</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>2</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>4</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>6</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>8</limit></action>
                            <action method="addPagerLimit" translate="label"><mode>list</mode><limit>all</limit><label>All</label></action>
                        -->
                    </block>
                    <reference name="newreference">
                        <block type="core/template" name="newreferenceblock" template="newreference.phtml" />
                    </reference>

                    <action method="addColumnCountLayoutDepend"><layout>empty</layout><count>6</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>one_column</layout><count>5</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>two_columns_left</layout><count>4</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>two_columns_right</layout><count>4</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>three_columns</layout><count>3</count></action>
                    <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>

                </block>
                    </block>

我在引用内部调用引用,事情是我想创建自己的侧边栏.那有什么问题呢？在list.phtml中,我通过以下方式调用我的引用:

<?php echo $this->getChildHtml('newreference') ?>

请帮我.

请使用以下方法(记住在内容下更新catelog.xml中的xml):

<?php echo $this->getLayout()->getBlock('yourblockname')->toHtml(); ?>
