How can I create a custom tag in Ivy

Question

Hi Ivy Team, I'm managing to create a custom tag in JSF. But it seems not work. Do I need to do something more ?

This is my custom class


@FacesComponent(createTag = true, tagName = "helloComponent", namespace = "http://example.com/tags")
public class HelloComponent extends UIComponentBase {
  @Override
  public String getFamily() {
      return "Greeting";
  }
  @Override
  public void encodeBegin(FacesContext context) throws IOException {
      String message = (String) getAttributes().get("message");
      ResponseWriter writer = context.getResponseWriter();
      writer.startElement("p", this);
      writer.write("Messageeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee: " + message);
      writer.endElement("p");

  }
}

This is my xhtml view : alt text

To use the component 2 things are required:

the component must be accessible by the tomcat webapp-classloader: so the compiled class must either:
- be copied as .class into webapps/ivy/WEB-INF/classes
- be copied as .jar into webapps/ivy/WEB-INF/libs
furthermore the component must be registered in the webapps/ivy/WEB-INF/faces-config.xml. You will see that our own IvyComponent is also registered there:

<component> <component-type>IvyComponent</component-type> <component-class>ch.ivyteam.ivy.dialog.execution.jsf.component.IvyCompositeComponent</component-class> </component>

And yes the approach has some limitations:

components must be part of your deployment process. So you should have an automated deployment chain with scripts that also deploy and register this component during project deployments.
designer requires a full restart before changes in faces-config.xml or changes in compile jar/classes are in effect.
