Replacement for IOnChangeListeer.INTERFACE

[Manfred Bergmann]

Hi.

We’ve tested Ajax components by code like this in Wicket 7:

val languageChoice = tester.getComponentFromLastRenderedPage("languageChoice").asInstanceOf[DropDownChoice[Locale]]
tester.getRequest.getPostParameters.setParameterValue(languageChoice.getInputName, "0")
tester.invokeListener(languageChoice, IOnChangeListener.INTERFACE)
assert(testPage.getLocale == Locales.supportedLocales.head)


In Wicket 8, IOnChangeListener.INTERFACE is not available anymore.
What is the recommended equivalent for this test?



Regards,
Manfred

Hi Manfred,

you probably already migrated from
#wantOnSelectionChangedNotifications() to a FormComponentUpdatingBehavior.

So you have to use that behavior as a listener now:

tester.invokeListener(languageChoice.getBehaviors(FormComponentUpdatingBehavior.class).get(0));

Hope this helps
Sven

Hi Sven.

I'm using the Kendo widgets. In particular the AjaxDropDownList.
It inherits from the Wicket standard DropDownChoice and hence I can add the
FormComponentUpdatingBehavior.
But that will throw a different error in the test:




Any ideas on that one?

OK, sorry. Forget that.
It seems to be working when adding the FormComponentUpdatingBehavior.
4 of 5 uses work. The last error I posted is probably due to something else,
model related.


Thanks,
Manfred
