Help with use of NavigationRequest in the UI

Hi,

I would like to understand the use of NavigationRequest - I saw this example in the vmware samples where we can create custom links whose click can navigate to object specific pages

/////////////////////////////////////////////////////////////////////////////////////////////

private function onLinkButtonClick(click:MouseEvent):void {

      // Jump to the Settings view

      var event:NavigationRequest = new NavigationRequest();

      event.targetViewUid = "com.vmware.samples.chassisCollection3.domainView"

      //event.context = ?????

      dispatchEvent(event);

   }

/////////////////////////////////////////////////////////////////////////////////////////////

The above navigation results in the global page - https://localhost:9443/vsphere-client/#extensionId=com.vmware.samples.chassisCollection3.domainView

However, there are other specific pages to which we would like navigation links. For example, in the above example, if we wanted to navigate to a specific context (say the chassis => summary page) like the following "https://localhost:9443/vsphere-client/#extensionId=com.vmware.samples.chassis.summary;context=com.vmware.core.model%3A%3…", then setting up the NavigationRequest seems to be tricky. It appears that it involves setting up the "event.context" to the "right" IResourceReference object.

My question is => How does one get access to the IResourceReference reference to a custom object in a view which does not carry the reference to the custom object. Can one derive the IResourceReference from the URI of a custom object? Please highlight the possibilities here.

Any help is appreciated.

Thank you
