Thanks, That is what I want , say for example I might have a bunch of higher level states from where at certain point I can navigate to child states defined in another xml like popup.xml, it will be nice If I can navigate from Wizard to popup by saying something like #popup/statename in the state transition logic of wizard itself. I hope this is possible !!

If using the Commons SCXML dialogs impl, this is possible. In fact, you don't even need to use '#popup' (at the cost of implying unique IDs for <state>s when subdialog state machines are pulled in via 'src' attribute -- see subdialogs bit here [1]). This has to do with the semantics of SCXML itself, which treats included state machines as white boxes (this differs from the basic impl) and thus, you can have dangling transition targets (as long as they're available in the included state machine -- or vice versa) as you mention above. Note that you don't even need to declare the included state machine as a <dialog> in the dialog-config.xml unless you plan on using it as a standalone dialog (at which point, the dangling unresolved transition target references will cause a parse time failure, if you choose to have them). -Rahul [1] http://shale.apache.org/shale-dialog-scxml/

If so, there's a way to do this that works for both SCXML and basic dialog implementations. The documentation[1] includes a bit of information on how to start a dialog programmatically using the DialogContextManager.create() call. But there is a second variation of create() that accepts a parent DialogContext with which the child dialog should be associated ... it will be set as the "parent" property of the new DialogContext for the popup. There's example code that accomplishes this in both the shale-dialog-test-basic and shale-dialog-test-scxml test applications (you'll need to check out the sources directly from the SVN repository to get to this code, however).
