add action to the root node of the object collection in vcenter web client sdk

Hi ,

I referred to the sample Chassis-ui plugin of vCenter web client SDK 5.1 .

I want to add actions like 'create chassis' on the root of the object Collection,not on the object 'chassis ' itself.

My code is same as the one provided in samples (chassis-ui plugin).

So,I am basically using vsphere.core.inventoryList.ObjectCollectionTemplate.So using the plugin,i am able to get the actions on each of the chassis object created.But if there are no objects created,actions are not seen at all,in the "Object" Tab of the root collection Node.So i want the actions on the root node,not on the object.

Please help.

Thanks a lot.
