This means that if the parent o:Cache
component clears its cache (e.g. because of time to live expiration), the value cached
by this value expression will be automatically cleared as well.
The direct parent of this component MUST be o:Cache
or a potential subclass of the associated UIComponent.
It's an error to have any other kind of parent.
The intended use of this is to explicitly cache a value expression that is used by one of the component children of o:Cache
,
so that even after a post-back (where the cached markup is of nu use) the original value expression will not be re-evaluated.
