How to enable one more global action based on flag.

I am usin vCenter web client SDK 5.5 .

I have created global action on the root of the object Collection.On selection of this global action,it gives custom popup which will take remote machine ip and authentication.If authentication is successfull, then I want to add/enable one more global action like 'create chassis' on the root of the object Collection.

Ho will i set flag in plugin.xml?

I am using vsphere.core.inventoryList.ObjectCollectionTemplate.So using the plugin,i am able to get the action on the root node.Using some flag,I want to enable one more global action which will inturn create chassis object.

Please help in this regard.
