share data between controllers

[former_member277448]

hello

i need to share data between controllers in the same app.

routing/navigation with parameters is not an option - there is no direct navigation between the controllers/views.

options being considered include having a 'global' model OR using an EventBus.

any thoughts/comments greatly appreciated.

any other options?

cheers

pas.

Hi Pas,

first of all: Don't store the data in a global object! Never do that! 🙂

Having a model on your Component does not all make it 'global'. It is still very well contained inside your application and does not disturb or pollute the launchpad or any other application.

// 'sending' controller
this.getOwnerComponent().setModel(oModel, "data");

// 'reveiving' controller
this.getModel("data")

That is probably the solution to go for.

you can put the model in component, which will be global, all the view can see it...

A model in the Component is explicitly NOT global. It is owned by the Component and propagated to it‘s children. A global model is what you set on the core with sap.ui.getCore().setModel()

i mean

Component.setmodel

my global mean "local" global......
