Testing RadioChoice with AjaxFormComponentUpdatingBehavior

[de...@dasberg.nl]

Hi all,

I am trying to test the ajax behaviour on a RadioChoice.

The RadioChoice has an AjaxFormComponentUpdatingBehavior which show/hide a
panel depending on its model value.


final Label label = new Label("label", "label");
label.setOutputMarkupId(true);
label.setVisible(false);
        
RadioChoice<Boolean> choice = new RadioChoice<Boolean>("choice",
Arrays.asList(Boolean.TRUE, Boolean.FALSE));
choice.add(new AjaxFormChoiceComponentUpdatingBehavior() {
    @Override
    protected void onUpdate(AjaxRequestTarget target) {
        RadioChoice<Boolean> choice = (RadioChoice<Boolean>)
getComponent();
        choice.updateModel();
        if(choice.getModelObject() == Boolean.TRUE) {
            label.setVisible(true);
        } else {
            label.setVisible(false);
        }
        target.addComponent(label);
    }
});

Now I can trigger the ajax behaviour by doing this:


tester.executeBehavior((AbstractAjaxBehavior)
getComponent("choice").getBehaviors().get(0));

now if I wanna check if the label component is visible I can do the
following:

tester.assertVisible("choice");

The problem is that the label isn't visible because the
respond(AjaxRequestTarget) method on
AjaxFormChoiceComponentUpdatingBehavior 
calls the getConvertedInput() method which sets the model to null.

I cannot use the formtester because I just need to check the visibility.

Does anybody know how to handle this?

Kind regards,

Mischa

Since nobody replied (yet) and I cannot believe that I am the only one
having this problem, and I found a way to bypass the problem I wanted to
share my solution

The executeBehavior method on the WicketTester looks like this.

public void executeBehavior(final AbstractAjaxBehavior behavior) {
        CharSequence url = behavior.getCallbackUrl(false);
	WebRequestCycle cycle = setupRequestAndResponse(true);
	getServletRequest().setRequestToRedirectString(url.toString());
	processRequestCycle(cycle);
}

During debugging I found out that the first thing that 
getServletRequest().setRequestToRedirectString(url.toString());
does is 

parameters.clear(); 

The problem is that I need the parameter because I want to know the value I
selected on the Component
that the Behavior is added to.

So i created a method on my Base Test class which looks like this:

 public void executeBehavior(String id, String value) {
        AbstractAjaxBehavior behavior = getComponentAjaxBehaviour(id);
        CharSequence url = behavior.getCallbackUrl(false);
        WebRequestCycle cycle = tester.setupRequestAndResponse(true);
       
tester.getServletRequest().setRequestToRedirectString(url.toString());
        tester.getServletRequest().setParameter(id, value);
        tester.processRequestCycle(cycle);
}

As you can see it doesn't look very different from the WicketTester version
only that 
I set the parameter before I call tester.processRequestCycle(cycle);

So now I can test my behavior. I don't know if this is the best way to go,
but for now 
I don't see any other way.

Kind regards,

Mischa
