Need help with "vsphere.core.menus.solutionMenus"

Hi,

I'm trying out the "vsphere.core.menus.solutionMenus" but I am not able to make it work. I'm not sure if I'm missing something. I'm very new to this.

By the way, I'm trying to hook it up with our own custom object. I tried it with Datastore and shows the menus but no luck with our custom object(ucp2k:Chassis).

<extension id="com.sample.actions.submenus">

    <extendedPoint>vsphere.core.menus.solutionMenus</extendedPoint>

    <object>

    <label>Chassis</label>

    <uid>allChassisActions</uid>

    <children>

    <Array>

    <com.vmware.actionsfw.ActionMenuItemSpec>

                     <type>action</type>

                     <uid>com.sample.actions.addAction</uid>

                     <label>Add</label>

                 </com.vmware.actionsfw.ActionMenuItemSpec>

                 <com.vmware.actionsfw.ActionMenuItemSpec>

                  <type>separator</type>

                 </com.vmware.actionsfw.ActionMenuItemSpec>

                 <com.vmware.actionsfw.ActionMenuItemSpec>

                     <type>action</type>

                     <uid>com.sample.actions.deleteAction</uid>

                     <label>Delete</label>

                 </com.vmware.actionsfw.ActionMenuItemSpec>

    </Array>

    </children>

    </object>

    <metadata>

    <objectType>ucp2k:Chassis</objectType>

    </metadata>

    </extension>

Please shed some light.
