After clicking on my custom menu item I see this screen without main menu and messages:

As you can see therre is no menu. Why? My atlassian-plugin.xml is:
<atlassian-plugin key="${project.groupId}.${project.artifactId}" name="${project.name}" plugins-version="2">
<plugin-info>
<description>${project.description}</description>
<version>${project.version}</version>
<vendor name="${project.organization.name}" url="${project.organization.url}" />
</plugin-info>
<component-import key="webResourceManager" interface="com.atlassian.plugin.webresource.WebResourceManager" />
<!-- Header Items -->
<web-item key="tokens" name="Tokens Management" section="topnav" weight="10">
<label key="Token management"/>
<link linkId="topnavTokensManagement">/console/secure/plugins/cargosoft/managetokens.action</link>
</web-item>
<!-- Application Components - Left-Hand Side -->
<web-section key="tokensnav" name="Tokens Navigation" location="left" weight="90">
<condition class="com.atlassian.crowd.plugin.web.conditions.SitemeshPropertiesCondition">
<param name="propertyName">meta.section</param>
<param name="propertyValues">tokens</param>
</condition>
</web-section>
<xwork name="Tokens Action" key="managetokens">
<package name="managetokens" extends="default" namespace="/console/secure/plugins/cargosoft">
<default-interceptor-ref name="defaultStack"/>
<action name="managetokens" class="com.cargosoft.crowd.plugin.TokensAction">
<result name="success" type="freemarker">/templates/view.ftl</result>
<result name="error" type="freemarker">/templates/view.ftl</result>
</action>
</package>
</xwork>
<resource type="i18n" name="i18n" location="messages.i18n" />
</atlassian-plugin>
and view.ftl is:
<html>
<head>
<title>Hello</title>
<meta name="decorator" content="atl.admin" />
</head>
<body>
Hello ${action.firstName} ${action.lastName}
</body>
</html>
How can I resolve this problem? and return main menu like at this picture???
