I'm in the middle of upgrading from 1.4.17 to 7.3 and one of many issues is
with the AjaxButton class that we extended. We provided three constructors
(id and form; id; id and model), an init function common to all three, and
an override of getAjaxCallDecorator().
Init function did a few
add(JavascriptPackageResource.getHeaderContribution(new
ResourceReference(OurAJaxButton.class, "filename.js")).
The override for getAjaxCallDecorator had a new IAjaxCallDecorator as a
parameter that had inplace overridesw for decorateScript,
decorateOnFailureScript, and decorateOnSuccessScript.
As near as I can tell, the replacement for the javascript stuff was
JavaScriptHeaderItem.forUrl("filename.js").
The replacement for the ajax decorator bit seems to have been
The strings inside there correspond, to the three decorate functions above,
except since they were actual method overrides, they did the js string + the
paramater (a CharSequence).
So that's all that was changed to get rid of the build errors. The actual
usage of the button hasn't changed. We just do in-place overrides for
onError(AjaxRequestTarget, Form) and onSubmit(AjaxRequestTarget, Form).
Nothing here had to change. We also have defaultFormProcessing false because
this is a cancel button. But for some reason, wicket prints the following
messages to the log and the onSubmit(AjaxRequestTarget, Form) override is
never entered.
We neither call these methods directly, nor are they overridden, so I'm not
sure what's going on here.
