web client callService(send request) to server has two wrong situations and how to implement nested menu

     Hi,

          I am developing vwc plug-in, I defined a new objectType for our device,and  implement navigator and objectView ,web client version is 5.5, and I got two questions, thanks.

1. Sometimes, web client callService(send request) to server has two wrong situations after browser refreshed.

        A. get error faultCode: Client.Error.DeliveryInDoubt faultString:'Channel disconnected' faultDetail: 'Channel disconnected before an acknowledgement was received'

        B. no response

        I try to do three things:

                a. add a alert before flex send request and call service

                b. add a alert in callback function

                c. add debug point to java service entry

        in case A, client got event error response, and program go to break point

        In case B, program doesn't go to break point, and no response.

1. How do I implement "Nested Actions Menu", and category actions in the default all actions sub-menu ( don't show uncategorized actions sub-menu ) ?

        I implement nested menu following vSphere Web Client Extensions Programming Guide 5.5. Example 7-7. Nested Solution Menu Extension with Action", but It's not work.

        I try to do two things for "Nested Actions Menu".

                a. remove <metadata><objectType>clisession</objectType></metadata>, let it be a global nested menu. It can show in another object action menu, but our object still not.

                b. I found a menu template like vsphere.core.menus.settings.serverObjectMenuTemplate,but the template is not in Table A-2 Extension Templates in the vSphere Web Client SDK.

                  I add a <templateInstance> to plugin.xml, and the nested menu is show in our object action menu. Do I need what king of menu template here?

Thank you
