-----------------------------------------------------------------
I've added the sources for a page and unit test that reproduce the issue.
Also I've found a workaround (see unit test), but it's not very elegant.

Page and unit test that reproduces to issue.
> Calling FormTester.select for DropDownChoice invokes onSelectionChanged with

> Key: WICKET-3977

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5-RC5.1
> Environment: Linux Ubuntu 11.04, Java 1.6.0_26
> Reporter: Marcel Cullens

> 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.
