I am trying few examples such as to display a canvas app which is built in SAP webDynpro. I am wondering if it is possible to exchange data between Canvas App and visualforce page where the app is embedded.
I understand that multiple canvas app on a visualforce page can exchange data between them through publish and subscribe methods. But is that possible to send and receive data between Canvas app and Visualforce page? I am assuming that we can send (POST) data to canvas app through parameters attribute in
<apex:canvasApp. Is that right?
For example if the canvas app is an "Add Order" page through which I can add an order. But once the order is created i need that newly created order number passed back to my visualforce page so that i can use it in apex to apply some logic and store the order id in order object in salesforce.
Any experts advice would be much apprciated.
