SCXML documents to describe Shale dialogs
"a modern web application framework, fundamentaly
based on JavaServer Faces". The Shale Framework includes a Dialog
Manager, to describe "conversations" or "dialogs"
(involving multiple views) with the user. Such a dialog is described
using a state-machine like declarative notation defined by the Shale
Framework. An alternative is using SCXML to describe the Shale dialogs
by introducing a
DialogNavigationHandler that uses the
Commons SCXML engine.
- SCXML semantics support parallelism, allowing multiple dialogs
to execute at the same time (a.k.a regions), and interact with each
other. This will be useful as Shale Dialog Managers evolve.
- The Commons SCXML implementation allows for registering listeners
that get notified as the state machine executes (onentry, onexit,
- Those developing multi-channel applications, or using frameworks
that use SCXML for the controller bits in other contexts (e.g.
RDC framework), may be inclined towards SCXML-based authoring for Shale
