[jira] [Created] (ISIS-2877) Support for Value Type Composition

Andi Huber created ISIS-2877:
--------------------------------

             Summary: Support for Value Type Composition
                 Key: ISIS-2877
                 URL: https://issues.apache.org/jira/browse/ISIS-2877
             Project: Isis
          Issue Type: Improvement
          Components: Isis Core, Isis Viewer Wicket
            Reporter: Andi Huber
            Assignee: Andi Huber
             Fix For: 2.0.0-M7


It should be sufficient to specify a value-type say CalendarEvent to be a compound of already existing value-types (date, time, duration, title, notes) = base-types, without the need of further integration with the UI.

Given all the required information via a ValueSemanticsProvider, the framework should be smart enough to handle:
* property update dialogs (optional -  for that to work, we might just require an update action that takes all required base-types as arguments)
* action dialogs (eg. just embed the base-types)
* table columns (eg. just embed the base-types, or as an alternative use value semantics 'rendering')
