Hi, I try to get the following combo to work.
package my.package.example.sender;
import org.osgi.service.component.annotations.Component;
import com.vaadin.addon.ipcforliferay.LiferayIPC;
import com.vaadin.annotations.Widgetset;
import com.vaadin.server.VaadinRequest;
import com.vaadin.ui.Button;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;
import lombok.extern.slf4j.Slf4j;
@Widgetset(AppWidgetSet.NAME)
@SuppressWarnings("serial")
@Slf4j
@Component(service = UI.class, property = { "com.liferay.portlet.display-category=category.sample",
"javax.portlet.name=Vaadin8SENDER", "javax.portlet.display-name=Vaadin 8 SENDER",
"javax.portlet.security-role-ref=power-user,user", "com.vaadin.osgi.liferay.portlet-ui=true" })
public class MySenderPortletUI extends UI {
private LiferayIPC liferayIPC;
public MySenderPortletUI() {
liferayIPC = new LiferayIPC();
liferayIPC.extend(this);
final VerticalLayout layout = new VerticalLayout();
setContent(layout);
final Button button = new Button("GO");
button.addClickListener(event -> {
log.info("BUTTON CLICK -> send EVENT");
liferayIPC.sendEvent("buttonClickedIPCEvent", "HALLO WORLD");
});
layout.addComponent(button);
}and the receiver class …
package my.package.example.receiver;
import org.osgi.service.component.annotations.Component;
import com.vaadin.addon.ipcforliferay.LiferayIPC;
import com.vaadin.annotations.Widgetset;
import com.vaadin.server.VaadinRequest;
import com.vaadin.ui.Label;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;
import lombok.extern.slf4j.Slf4j;
@Widgetset(AppWidgetSet.NAME)
@SuppressWarnings("serial")
@Slf4j
@Component(service = UI.class, property = { "com.liferay.portlet.display-category=category.sample",
"javax.portlet.name=Vaadin8RECEIVER", "javax.portlet.display-name=Vaadin 8 RECEIVER",
"javax.portlet.security-role-ref=power-user,user", "com.vaadin.osgi.liferay.portlet-ui=true" })
public class MyReceiverPortletUI extends UI {
Label label = new Label("");
private LiferayIPC liferayIPC;
public MyReceiverPortletUI() {
liferayIPC = new LiferayIPC();
liferayIPC.extend(this);
final VerticalLayout layout = new VerticalLayout();
setContent(layout);
layout.addComponent(label);
liferayIPC.addLiferayIPCEventListener("buttonClickedIPCEvent", event -> {
log.info("receive EVENT: " + event.getData());
label.setCaption(event.getData());
});
}
}I got the following error within the broser (/?debug=)
