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.
