conversation and back buttons
When i have a conversation that already started(by invoking method annotated with @begin, and
1.) I press back button and
2.) click on a submit button, it brings me back to the page where the current state should be, this it shows a message "Illegal navigation" this is fine, it's the page where the user should be.
3.) i click any button
However, now it bombs out. I must be doing something wrong as the tutorial had stated that free navigation is supported and handled.
Here is the exception:
