Hi Dilshan, You don't quite have this right.
It's still necessary to annotate the view model with @DomainObjectLayout, and optionally to specify a titleUiEvent, eg [1] The event subscriber then checks for the event on the JAXB view model, eg [2] If you didn't want to annotate the JAXB view model with @DomainObjectLayout, then you could instead write a custom facet factory that looked for the JAXB @XmlRootElement and did the same job; details in [3]. I've raised ISIS-1337 for this idea [4] HTH Dan [1] https://github.com/isisaddons/isis-app-todoapp/blob/master/dom/src/main/java/todoapp/app/viewmodels/todoitem/v1/ToDoItemV1_1.java#L43 [2] https://github.com/isisaddons/isis-app-todoapp/blob/master/app/src/main/java/todoapp/app/services/titlesubscriber/UiEventSubscriber.java#L41 [3] http://isis.apache.org/guides/ugbtb.html#_modifying_the_prog_model [4] https://issues.apache.org/jira/browse/ISIS-1337 On 2 March 2016 at 09:55, Shan Wijesinghe <shandwijesin...@gmail.com> wrote: > * Please ignore the mismatch between the Myclass_viewmodel and it's > constructor named as TrsItem_ViewModelTrs > > On Wed, Mar 2, 2016 at 3:18 PM, Shan Wijesinghe <shandwijesin...@gmail.com > > > wrote: > > > Thank you for the information Dan. > > > > I did the following.
