Hi Dan, I had some trouble reading my mail (not sending though...) so I missed a lot of updates on this thread. Thanks for your quick implementation! I will look at it asap.
I think the wizard should be part of the wicket-viewer but when all add-ons can be found on one clear website it shouldn't be a problem to make it an add-on, though.

I don't think about it as a widget/component, but a different way to render the UI, including page navigation. But that's really subjective, so do whatever you think is best. Perhaps you're considering future add-ons corresponding to other UI designs as future add-ons. What it's really important as seems for all other mailing list users is that you've developed it. Thanks!

I've also raised ISIS-810 [2], which removes the component from Isis; but since we aren't yet decided on whether we want this component in or out, have only pushed that as a branch, not to master. Meanwhile, I have also created a new github repo to house this component if we decide to keep it outside of Isis, see [1] ~~~ Related, yesterday Jeroen and I created a new github account, "isisaddons" [4], as a place to hold future add-ons. All of my various github projects could either move or be forked there. We've also grabbed "isisaddons.org<http://isisaddons.org/>" as a domain if we decide to follow the approach taken by Apache Wicket with their wicketstuff.org<http://wicketstuff.org/> companion project [5]. ~~~ Thoughts on any of this welcome Dan [1] https://issues.apache.org/jira/browse/ISIS-807 [2] https://issues.apache.org/jira/browse/ISIS-810 [3] https://github.com/danhaywood/isis-wicket-wizard [4] https://github.com/isisaddons [5] http://wicketstuff.org/ On 13 June 2014 19:52, GESCONSULTOR - Óscar Bou <o....@gesconsultor.com<mailto:o....@gesconsultor.com>> wrote: But if the annotations are part of the "Isis model", shouldn't be a default implementation included on the free Viewer? Independently, the implementation could be replaceable / pluggeable with a custom one, just as any other components. But at least one should be included by default. I also think that it adds quite points to the quickstart demo, as it's an alternative design to usual Isis UI. But that's completely subjective, of course :-)) HTH, Oscar El 13/06/2014, a las 13:27, Dan Haywood <d...@haywood-associates.co.uk<mailto:d...@haywood-associates.co.uk>> escribió: Further improvements committed, tickets ISIS-781 and ISIS-800 marked as resolved Discussing off-line with Jeroen, do have some further refactorings planned, however. Specifically: ... currently support for IWizard is "hard-coded" into the Wicket viewer; it ought to be a pluggable component (such as the map and calendar components). So will probably move it out and into a separate github repo. One consequence of that is that the quickstart todo app can't demonstrate the usage. So I'll need to move that into a github repo as a separate demo. One upside is that this ought to then plug into 1.5.0, rather than relying on a new release of Isis. Also, it'll be a good resource for how to write custom components to the Wicket viewer. But the basic functionality will be as currently implemented. More to follow....

The way it works is that the view model is immutable so far as the rest of the framework is concerned, but (by implementing the Cloneable interface) when the view model is next re-rendered it is actually the clone. for the second, the view model must implement Wizard. This is actually a sub-interface of ViewModel.Cloneable that defines next, previous and finish methods. The todo/quickstart app has been updated to use this feature; see ToDoItemWizard. See also the cool use of contributed actions through the "Categorized" interface that contributes both to ToDoItemWizard and also the ToDoItem entity. ~~~ The design as it stands does mean there's a little bit of boilerplate to implement these various methods, but what we now have is probably good enough to ship in the next release.

But getting the subscription (or a property) for the ViewModel rendering gives a null pointer exception. A stack trace would be useful. But just to check: you have configured the MementoServiceDefault and the BookmarkServiceDefault ? I looked at the ToDoItem examples and Dileepa's code. I can see no conceptual difference except that ToDoItem uses persisted entities and Dileepa only sets the memento and does not pass more 'complex' objects in the ViewModel. Do the objects have to be serializable or do I miss something else? This is probably the issue. Making the object serializable might solve things, but it's rather unpalatable. Rather than creating a transient object, instead have the wizard store the state (ie the builder pattern), and only create (and persist) the object when done. ~~~ Isis does, in fact, have the ability to create serializable mementos even from non-serializable transient objects (a left over from the days when Isis' architecture was client/server); but this isn't currently exposed in a user-friendly applib service. We could look to doing so if the above approach is unpalatable, eg as an extension of MementoService. Dan Any idea?

It looks like the ViewModels only work with persisted entities. Is that correct? Not exactly. A view model can hold references to any data; that's what the MementoService is for. Our Google Summer of Coder (Dileepa) has written a view model that wraps some JSON representing a gmail obtained via a web service, for example. Fundamentally a view model just has the ability to marshall itself to/from a string. We use that string as its OID, which appears in the URL. When we next interact with the view model, Isis recreates the view model from that OID. What the view model does with its string is up to it. What I try to accomplish right now (as a work around) is to return a ViewModel from an action with the posted data from the action put into that viewmodel and than call some actions on that viewmodel. If it is possible to return a fresh viewmodel every time I return from an action, it looks a bit like a wizard. At least I can build some data model in memory and persist this model when ready. Should that be possible? Yup, that's the best we can offer for now. I will elaborate my wishes in the ticket you raised. Wat is the use of a @NotPersistable-entity like described in [1]? It was a way of saying that an object can never be persisted, ie a domain constraint. But when using JDO objectstore it is somewhat redundant (or at least not fully implemented), because we delegate the responsibility for doing persistence to JDO/DN. When Isis 2.0 comes along, some of these older annotations might end up being deprecated/removed.

And we should. I agree that @NotPersistable is confusing and its not clear what to use; the right solution would be to implement a view model (currently: implement the ViewModel interface), and then - optionally - write a custom ComponentFactory for the Wicket viewer to render the wizard appropriately. But the snag even with the above is that (currently) view models are immutable; they support actions but their properties cannot be edited. I can see the way forward on this; I don't think it's difficult, but it will require a change in core and probably the wicket viewer also. If you want then raise a ticket for this requirement, and sketch how you'd like it to work.
