Hi Bharani, thanks for putting together that demo.
So, the reason that those two actions don't appear - "addToState" and "removeFromState"- is because of an unimplemented feature of the Wicket viewer. You'll have seen that properties, collections and actions all have the concept of supporting methods. For property, getXxx()/setXxx(...), we have hideXxx(), disableXxx(), validateXxx(...), defaultXxx(), choicesXxx(), autoCompleteXxx() . There are also the little used modifyXxx(...) and clearXxx(...), which are called instead of the setter if present. These were originally to support mutual registration pattern for bidir relationships, but are not generally needed these days because JDO/DN (the ORM) handles this for us. For collection getYyy()/setYyy(...) we have hideYyy(), disableYyy(), addToYyy(...), removeFromYyy(...), validateAddToYyy(...), validateRemoveFromYyy(...). The idea of the addTo and removeFrom is to allow objects to be added or removed from the collection (assuming that the collection is mutable). For action zzz(...) we have hideZzz(), disableZzz(), validateNZzz(...), defaultNZzz(), choicesNZzz(), autoCompleteNZzz(). The unimplemented feature in the Wicket viewer is that it doesn't support the notion of mutable collections. That is, if there is an addTo and removeFrom then the underlying metamodel says that the collection is mutable, but the Wicket viewer just ignores it. (Note that the RO viewer *does* support mutable collections). So, this is why your "actions" are being ignored... because they aren't being recognized as actions, they are being recognized as supporting methods of the collection. Fix: - rename addToStates to addState - rename removeFromStates to removeState There's probably a ticket for this; if you are feeling inspired, see if you can find it (or raise a new one to get this addressed somehow). HTH Dan PS: spend some time setting up fixtures, it'll save some time. PPS: Also, uncomment #isis.viewer.wicket.rememberMe.encryptionKey=myEncryptionKey in viewer_wicket.properties, to save having to log in all the time.
