[jira] [Commented] (WICKET-3977) Calling FormTester.select for DropDownChoice invokes onSelectionChanged with null argument

Mathijs de Groot commented on WICKET-3977:
------------------------------------------

I'm struggling with the same issue.
I think every developer that uses Forms with Dropdowns (and writes good Unit tests) will face this issue.
@Marcel: Thanks for the (not very elegant) workaround. Hope this issue will be fixed soon.

> I have a DropDownChoice which has a wantOnSelectionChangedNotifications that returns true, so that the onSelectionChanged is called when the selection changes.
> In a unit test a selection is made for the dropdown using: formTester.select("dropDown", 0);
> The FormTester sets the selected value for the dropdown as a post parameter in the current request and the calls BaseWicketTester#executeListener to process the request for the onSelectionChanged event.
> In BaseWicketTester#executeListener however the the request post parameters previously set are ignored, by creating a new empty request:
> MockHttpServletRequest request = new MockHttpServletRequest(application, httpSession, servletContext);
> I guess either the current request should be used instead of new-ing one or the post parameters should be copied from the current request instance.
