I want to trigger the screen to go out and get new data only when:
1. the user enters the specific viewstack sub screen, and
2. when the data for that screen is dirty, based on some bound data that has triggered a change
So as I see it, the screen needs to keep track of when the bound field has changed which should cause a call to get fresh data. This means that the screen must keep track of whether it is dirty.
This seems like it must be a common scenario, and I am curious about how other people handle it. My first instinct was to create a base screen class from which all my screens could inherit. But I am curious whether cairngorm already handles this or whether this is even part of the scope of what it tries to cover. I am not using cairngorm right now, but may in the future. But understanding what is and isnt in its scope is important for me to start to understand.
So anyway, this is a 2 part question.
1. how do people handle this situation
2. does cairngorm have some pre-packaged solution to this issue.
