here is the current working mixin. It uses markup writer to set the button
value because
submitLabel = defaultLabel; will result in the error
public class BeanEditDefaults {
@BindParameter
private String reorder;
@BindParameter
private String submitLabel;
@Inject
private Environment environment;
@Inject
private ComponentResources resources;
@Inject
private Logger logger;
private Element form;
private String newLabel;
@SetupRender
@SuppressWarnings("unchecked")
void setupRender(MarkupWriter writer) {
String defaultLabel =
resources.getContainerResources().getMessages().get("submit-label");
logger.info("default {}", defaultLabel);
if (submitLabel != null && submitLabel.equals(defaultLabel)) {
form = writer.element("mixin", "name",
this.getClass().getName());
String type =
resources.getContainerResources().getBoundType("object").getSimpleName();
newLabel =
resources.getPage().getComponentResources().getMessages().format("submit-label",
type);
environment.peek(LayoutEnvironment.class).setTitle(newLabel);
}
Class beantype =
resources.getContainerResources().getBoundType("object");
BeanEditEnviromentInterface enviromentType =
(BeanEditEnviromentInterface)
beantype.getAnnotation(BeanEditEnviromentInterface.class);
if (enviromentType != null) {
BeanEditEnvironment defaults =
environment.peek(enviromentType.value());
if (defaults != null) {
if (reorder == null) {
reorder = defaults.getOrder();
}
}
}
}
@AfterRender
void afterRender(MarkupWriter writer) {
if (form != null) {
writer.end();
form.visit(new Visitor() {
public void visit(Element element) {
if (element.getName().equals("input")) {
String value =
element.getAttribute("value");
String type =
element.getAttribute("type");
if (type != null &&
type.equals("submit")
&& value !=
null && value.equals(submitLabel)) {
element.forceAttributes("value", newLabel);
}
}
}
});
}
}
@CleanupRender
void cleanupRender() {
if (form != null) {
form.pop();
}
}
}
It's attached with a worker
public class AddMixinWorker implements ComponentClassTransformWorker2 {
public void transform(PlasticClass plasticClass, TransformationSupport
support, MutableComponentModel model) {
if ( match(BeanEditForm.class, plasticClass) ) {
model.addMixinClassName(BeanEditDefaults.class.getName());
}
}
boolean match( Class clazz, PlasticClass plasticClass) {
return clazz.getName().equals(plasticClass.getClassName());
}
}
