Doubt about MVP & multiple areas.

[vehdra music]

I need to have a layout like this.

+----------------------------------------------+
|                                                        |
+----------------------------------------------+
| Users |   Name        [            ]         |
| Pages|    Lastname [            ]         |
|           |                                            |
|           |    [Save][Cancel]                 |
|           |                                            |
|           |-------------------------------------|
|           | [Add]                                   |
|           |-------------------------------------|
|           |  Id | Name | Lastname        |
|           |                                            |
|           |                                            |
|           |                                            |
+----------------------------------------------+

In the lateral panel (Users / Pages) I have my "main menu". When a user clicks on the "Users" menu item, in the gray area I have to display an "Add" button and a table of users.

When the user clicks in the "Add" button, I have to show a form over the Users table and hide the "Add" button.

What I did is the following:

I created two ACP (Activity / View / Place):

1. UsersEditPlace, UsersEditView (here I have the form), UsersEditActivity
2. UsersListPlace, UsersListView (here I have the table, and the Add button), UsersListActivity

And, I also created two ActivityMappers:

1. TopActivityMapper for the green area.
2. MainActivityMapper for the grey area.

The only trouble that I have is: how can I set visible 'Add' button" when the user clicks in the "Cancel" button of the form (UserEditView) ?

Because, the "Cancel" button is in my UsersEditView, and the "Add" button is in my UsersListView, I don't have any reference to that button.

I thought maybe, to implement PlaceHandler on my UsersListView, and if the Place is instance of UsersListPlace setVisible(true) to the button, but I don't like this idea so much.

On the other side, where is placed the "Add" button, I have to put a menu for almost every item in my main menu (lateral menu) should I have another ActivityMapper where is my Add button, and create a View / Activity for every menu that I have to create?

With regards to enabling your add button, throw a custom event on the click of cancel, listen for this event in the activity which manages the view containing the add button.
