How do you get an object from one Place to another?
For example, I have a ContactsView with a table of Contacts, and the corresponding ContactsActivity/Place classes. If I want to edit a contact, I click on the table row and go to the ContactEditorPlace. How does the ContactEditorView get the Contact to edit?
The examples I've seen seem to make a point of not passing actual object references in the Place, but instead they go to the trouble of passing a String or id (e.g., the Expenses sample). Is there any reason for this other than easy tokenization? Is there some reason a reference should not be in a Place?
If the object reference is not set in the constructor of the ContactEditorPlace, then how does it get to the ContactEditorActivity? This could be done with the EventBus, but that would be a lot of boilerplate to pass a single reference to a single activity.
I would remark that I am not using RequestFactory.
In my opinion :
There's no problem passing object references in the place's constructor. That way you can easily pass the Contact reference when clicking on the row you want to edit.
However it's probably not a good idea to use that whole object as the token. I think it's best to use it's id and then fetch the object from the id when detokenizing and pass it to the constructor.
As far as the Expenses example, i believe it's because they use the Request Factory which has those Entity Locators that make it easy to fetch entities based on their ids.
