I am trying to navigate through views in my application and I suddenly get this in the console of debugger like: com.vaadin.client.VConsole SEVERE: Server response didn't contain an id
And I getting this error message at the top of my page. Communication problem Take note of any unsaved data, and click here or press ESC to continue. I am using VAADIN 7.2.0 And I was on 7.1.13 before with the same error. Please I need anyone's suggestion to solve this issue it's really annoying.
