插件开发，扩展了popMenus，开始右键不出现扩展的菜单项

[violet827]

plugin.xml中代码片段如下：

<extension
point="org.eclipse.ui.popupMenus">
<objectContribution
adaptable="true"
id="test.objectContribution1"
objectClass="nc.uap.studio.mde.ext.navigator.adapters.BComponent">
<action
class="test.ui.actions.MultiBillAction"
icon="icons/multibill.png"
id="test.action3"
label="%wizard.name">
</action>
<action
class="test.ui.actions.SingleTreeAction"
icon="icons/singletree.png"
id="test.action2"
label="%wizard.name.2">
</action>
<action
class="test.ui.actions.SingleDocAction"
icon="icons/singledoc.png"
id="test.action1"
label="%wizard.name.1">
</action>
<action
class="test.ui.actions.SingleBillAction"
icon="icons/singlebill.png"
id="test.action4"
label="%wizard.name.0">
</action>
</objectContribution>
</extension>

如果不出扩展菜单项，可以从哪儿看看日志来进行问题分析吗，看.metadata/log里没有输出任何日志
