Hi Roger Thanks for the quick reply. Sorry for my delayed response.
I am trying to get a handle on implementing an MVC application using Pivot. At this point I am seeing Pivot as the MVC “View", and am searching for hooks that can relate the data contained in the model to the Pivot “View”. View – The view renders the contents of a model. It specifies exactly how the model data should be presented. If the model data changes, the view must update its presentation as needed. This can be achieved by using a push model, in which the view registers itself with the model for change notifications, or a pull model, in which the view is responsible for calling the model when it needs to retrieve the most current data. https://lkubaski.wordpress.com/2012/12/20/java-se-application-design-with-mvc-with-images/ <https://lkubaski.wordpress.com/2012/12/20/java-se-application-design-with-mvc-with-images/> The application is complicated by the fact that model data is interrelated. In other words, if a column in a row is updated, other columns may have to be updated as well. These relationships can be encoded in an “intermediate representation” of the model data. I’m pretty sure Pivot has everything to do what I need to do. After long involvement with synchronous systems, I’m just struggling to get a handle on the architecture. Thanks!
