WicketTester -- No Form onSubmit when using Ajax DropDownChoice Component
Hi All,
I'm having an issue when using WicketTester with a form that has 3
DropDownChoice component, which are linked together using the
AjaxFormComponentUpdatingBehavior. In the following code snippet,
selecting from the "brands" DropDownChoice causes the "categories"
DropDownChoice to be filled. Then, selecting from the "categories"
DropDownChoice causes the "titles" DropDownChoice to be filled.
All of this works fine. However, the call to formTester.submit()
does not trigger the form's onSubmit method. Any ideas what I am
doing wrong? This is using Wicket version 1.3.7.
Thanks,
Steve
----------
WicketTester tester = new WicketTester(webapp);
tester.setupRequestAndResponse();
FormTester formTester = tester.newFormTester("mainPanel:officeSelectorForm");
formTester.select("brands", 0);
tester.executeAjaxEvent("mainPanel:officeSelectorForm:brands", "onchange");
tester.assertComponentOnAjaxResponse("mainPanel:officeSelectorForm:categories");
formTester.select("categories", 0);
tester.executeAjaxEvent("mainPanel:officeSelectorForm:categories", "onchange");
tester.assertComponentOnAjaxResponse("mainPanel:officeSelectorForm:titles");
formTester.select("titles", 0);
formTester.submit();

OK, I think I get it now Martin:
----------
WicketTester tester = new WicketTester(webapp);
tester.setupRequestAndResponse();
FormTester formTester4Ajax =
tester.newFormTester("mainPanel:officeSelectorForm");
formTester4Ajax.select("brands", 0);
tester.executeAjaxEvent("mainPanel:officeSelectorForm:brands", "onchange");
tester.assertComponentOnAjaxResponse("mainPanel:officeSelectorForm:categories");
formTester4Ajax.select("categories", 0);
tester.executeAjaxEvent("mainPanel:officeSelectorForm:categories",
"onchange");
tester.assertComponentOnAjaxResponse("mainPanel:officeSelectorForm:titles");
FormTester formTester4Submit =
tester.newFormTester("mainPanel:officeSelectorForm");
formTester4Submit.select("brands", 0);
formTester4Submit.select("categories", 0);
formTester4Submit.select("titles", 0);
formTester4Submit.submit();
----------
Not quite sure why it works but it does. Thanks very much =)

I am confused by something here. I am using the calls to
tester.executeAjaxEvent() in order to populate
the DropDownChoice components with items (these items are provided by a
mocked service layer).
Then I call formTester.select() in order to pick from the items provided by
the tester.executeAjaxEvent()
calls. These selected items are then used with the call to
formTester.submit().
Are you saying that tester.executeAjaxEvent() and formTester.select()
cannot be used together?
If so then what would be the best way to supply the DropDownChoice items in
order to properly
call formTester.submit()?
Thanks!

Ah.. then the answer is: formtester can be used only for single
submit. For a new one, make a new one. It would be nice if it threw an
exception (maybe create jira issue for that?).

Hi Martin,
Thanks for the quick reply. The onSubmit method of my form does actually
work with the 3 linked
DropDownChoice components, when used as part of my application. I am trying
to simulate this
functionality as part of an integration test, and that's when the onSubmit
method is not triggered.
So I assume it's some misunderstanding on my part as far as WicketTester is
concerned, not
about using AjaxFormComponentUpdatingBehavior for components within a form.
Steve

Hi!
AjaxFormComponentUpdatingBehavior does not submit the other form
values, only the involved component. If you want to handle other form
values you will need something like AjaxFormSubmitBehavior or
AjaxFormSubmittingChangeListenerBehavior:
public abstract class AjaxFormSubmittingChangeListenerBehavior extends
AjaxFormSubmitBehavior {
private final static Method hiddenFieldGetter;
static {
try {
hiddenFieldGetter = Form.class.getDeclaredMethod("getHiddenFieldId");
hiddenFieldGetter.setAccessible(true);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* @see org.apache.wicket.ajax.AbstractDefaultAjaxBehavior#onBind()
*/
@Override
protected void onBind() {
super.onBind();
if (!(getComponent() instanceof IOnChangeListener))
{
throw new WicketRuntimeException("Behavior " + getClass().getName() +
" can only be added to an instance of a IOnChangeListener");
}
}
/**
* @param event
*/
public AjaxFormSubmittingChangeListenerBehavior(String event) {
super(event);
}
/**
* @see org.apache.wicket.ajax.form.AjaxFormSubmitBehavior#onError(org.apache.wicket.ajax.AjaxRequestTarget)
*/
@Override
protected void onError(AjaxRequestTarget target) {
onSubmit(target);
}
/**
* @see org.apache.wicket.ajax.form.AjaxFormSubmitBehavior#onEvent(org.apache.wicket.ajax.AjaxRequestTarget)
*/
@Override
protected void onEvent(AjaxRequestTarget target) {
HttpServletRequest httpServletRequest = ((WebRequest) getComponent()
.getRequest()).getHttpServletRequest();
Map parameters;
if (httpServletRequest instanceof MockHttpServletRequest) {
parameters = ((MockHttpServletRequest)
httpServletRequest).getParameterMap();
} else {
parameters = ((org.mortbay.jetty.Request)
httpServletRequest).getParameters();
}
parameters.put(getHiddenFieldId(getForm()),
getComponent().urlFor(IOnChangeListener.INTERFACE));
final FormComponent<?> formComponent = (FormComponent<?>) getComponent();
try {
if (isUpdateModel()) {
formComponent.inputChanged();
formComponent.validate();
if (!formComponent.hasErrorMessage()) {
formComponent.valid();
formComponent.updateModel();
}
}
super.onEvent(target);
} catch (RuntimeException e) {
Utils.errorLog(AjaxFormSubmittingChangeListenerBehavior.class, e);
onError(target);
}
}
/**
* @return boolean
*/
protected boolean isUpdateModel() {
return true;
}
/**
* @param form
* @return String
*/
private String getHiddenFieldId(Form<?> form) {
try {
Form<?> root = form.getRootForm();
return (String) hiddenFieldGetter.invoke(root);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
