I've just spent several hours trying to debug a rather strange effect with a dropdown and a AjaxFormComponentUpdatingBehavior.
I have a component which is used in several places of the system. It contains a dropdown to which a AjaxFormComponentUpdatingBehavior is added. Whenever the user selects a value, a label is displayed underneath. This component has been in use in different parts of the system for quite some time now. After having upgraded to Wicket 6.6, it does no longer work - on one particular page. While on all other pages it works just fine, on that particular page every time I change something, the page reloads (just as if I had attached an AjaxFormSubmitBehavior (which of course I had not, actually there is not a single one used within the whole project). When doing this reloading, my AjaxFormSubmitBehavior's handler is never invoked. I checked the requests the browser gets to see, and it seems like there isn't any difference. Just in case, here's roughly what I get on the pages where it works: Path: http://localhost:8080/editor/editorial-tools/rundschreiben?7-1.IBehaviorListener.1-page~body-stage-stage_content-wrapped_content-content-editor-form-object_editor-groups-0-group-attributes-7-item-value-choice-ajax~holder-drop~down&rubrik=Rundschreiben Method: POST The next request is an icon for the stuff displayed later. On the "bad" page, the request does not look too much different (it's just a different page): Path: http://localhost:8080/foo/bar/nav/foobar-xxx?14-1.IBehaviorListener.1-page~body-stage-stage_content-wrapped_content-foo~content-choice-ajax~holder-drop~down&action=new&variant=foo-sub-page Method: POST Only after it, I get the original path, but a redirect: : Path: http://localhost:8080/foo/bar/nav/foobar-xxx?action=new&variant=foo-sub-page Method: GET Status Text: 302 (Moved Temporarily) Now this indicates that something's going wrong in the Java code rather than in Javascript. I tried to find the point where the multiplexing is done and from where the Ajax behaviours are invoked, but I did not find it. Now I feel really clueless. Is there a wellknown Gotcha which simply I don't know of? Maybe anybody had the same problem before? Or, at least, where should I step into the Wicket code in order to find out where it goes wrong? Any help appreciated!
