Is it possible to add a session in cq:dialog which renders whatever data is supplied in the fields and previews it out in real time. In the simplest of scenarios, I need to add two numbers and when I enter both the numbers the cq:dialog should preview it's output as 4. There should be two sessions in the the cq:dialog, like two columns, the left one to enter value to the fields and the right to display the rendered output. How to achieve this? Is it possible to?
