Buffer requested actions while not connected

[aurelien-baudet]

For example, I have an Angular app that routes the url #/user/:userId to the UserPage page. The first thing done by this page is to load user information (firstname, lastname, ...) from ZP using the SDK (call to getUserInfo()).

When I navigate through Angular, the application is already started and the user is already connected so calling the getUserInfo() works.
However, when I enter the url in the browser or when I hit F5, the Angular applications loads directly the page and the call to getUserInfo() fails because the user is not connected (message : "Illegal state: already disconnected").

So when no connection is opened, the SDK should "replace" the real call by storing channel and parameters into a FIFO. As soon as the connection is avaiable, reexecute the pending actions stored in the FIFO and allow to call the real functions.
