So the @Parameter can only be used to passed user-defined data structure to
the custom component...
Is there a way such that the page that displays the custom component can
have access to the componet's properties (public getter functions) in order
to retrieve the user-defined data structure? For example, in the page's
onSuccess method, I want to retrieve a List<MyDataStructure> from my custom
component, how can I do that?
thx!
