  Note: The reference can be to the static or virtualized properties, but if a property type is virtualized and the property is not found, a fall-back to search the application for the static non-virtualized property IS NOT PERFORMED.

  Calling this method is the same as calling getRuntimePropFromReference(reference, false)}.

  Specified by:

  getRuntimePropFromReference in interface IAppSessionGyro

  Specified by:

  getRuntimePropFromReference in interface IRuntimeReferenceLookup

  Parameters:

  reference - The reference to look-up.

  Specified by:

  getRootFromName in interface IAppSessionGyro

  Specified by:
