Views Related to Virtual Targets
--------------------------------
From a node usually any object in the concept or resource space can
be accessed as a `virtual target`. This is done by putting ".targetNNN"
at the end of the URL, with NNN being the unique id of the concept
or resource.

Virtual Targets
---------------
From a node usually any object in the concept or resource space can
be accessed as a `virtual target`. This is done by putting ".targetNNN"
at the end of the URL, with NNN being the unique id of the concept
or resource.
>>> from loops.view import NodeTraverser

>>> view.virtualTargetObject

A virtual target may be edited in the same way like directly assigned targets,
see above, "Editing an Object". In addition, target objects may be viewed
and edited in special ways, depending on the target object's type.
In order to provide suitable links for viewing or editing a target you may
ask a view which view and edit actions it supports. We directly use the
target object's view here:
>>> view.virtualTarget.getActions()
[<loops.browser.common.Action object ...>]
>>> action = view.virtualTarget.getActions()[0]
>>> action.url
'http://127.0.0.1/loops/views/m1/m11/m111/.target16'
