Subject [jira] Commented: (SHALE-175) Dialog statemachine and errorconditions should be queryable

Adam Brod commented on SHALE-175:
---------------------------------

It seems that using the back-button will often get the dialog into the intractable error state.
 We don't have to be super back-button friendly, but we can't pollute the user's session and
give them errors on everything they do, just because they hit the back button one time.

> Having been fiddling around with the Shale dialogs, there is one thing that I feel could
be improved on. The way it is now, if there is an error situation or if the user navigates
away from a dialog and later on navigates to say the start of the dialog, an exception is
raised. There is no way out of this, short of restarting the server. I think a more elegant
sultion would be if the state-engine could be queried by for instance the bean that kicks
off the dialog sequence. This way one could present a  more meaningful and customizeable feedback
to the user.
