[jira] Created: (SHALE-175) Dialog statemachine and errorconditions
should be queryable
Dialog statemachine and errorconditions should be queryable
-----------------------------------------------------------
Key: SHALE-175
URL: http://issues.apache.org/struts/browse/SHALE-175
Project: Shale
Type: Improvement
Components: Core
Versions: 1.0.3
Reporter: Hermod Opstvedt
Hi
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.

[jira] Commented: (SHALE-175) Dialog statemachine and

---------------------------------
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.

--------------------------------------------
one of the problem is that the exception raised is very generic (ie IllegalArgumentException). I think it could be at least changed to something a bit more specific, for example : ShaleStateMachineUnsynchronizedException or whatever instead of the IllegalArgument.
Without needing a too much complex change that seems to be needed to fix the whole stuff, it could add a way to deal with the issue.
