Edit the ViewSourceActionComponent class as below:

}
)
public class ViewSourceActionComponent extends AbstractEventActionComponent {
public static final String ACTION = "ViewSource";
private static final List<UIExtensionFilter> FILTERS = Arrays.asList(new UIExtensionFilter[] { new IsViewModeFilter() });
@UIExtensionFilters
public List<UIExtensionFilter> getFilters() {
return FILTERS;
}
@Override
public String getActionName() {
return ACTION;
}
@Override
public boolean isAnchor() {
return false;
}
public static class ViewSourceActionListener extends MoreContainerActionListener<ViewSourceActionComponent> {
@Override
protected void processEvent(Event<ViewSourceActionComponent> event) throws Exception {
UIWikiPortlet wikiPortlet = event.getSource().getAncestorOfType(UIWikiPortlet.class);
UIWikiContentDisplay contentDisplay = wikiPortlet.findFirstComponentOfType(UIWikiPageContentArea.class)
.getChildById(UIWikiPageContentArea.VIEW_DISPLAY);
PageImpl wikipage = (PageImpl) Utils.getCurrentWikiPage();
contentDisplay.setHtmlOutput(wikipage.getContent().getText());
event.getRequestContext().addUIComponentToUpdateByAjax(contentDisplay);
}
}
}
Some remarks:
The action name is ViewSource.
The listener class name = the action name + "ActionListener" (so it is ViewSourceActionListener).
In this example, the listener extends the MoreContainerActionListener class. As a result,
the action will be added to the More menu in the Wiki portlet.
There are some choices that will be introduced later.
At the ComponentConfig annotation, you see a gtmpl file is given.
Here you re-use the templates/wiki/webui/control/action/AbstractActionComponent.gtmpl file
that is already packaged in wiki.war.
