i did some partial page rendering (PPR) myself ... but i don't
know it is the tapestry 5 way of doing it...
rendering a component from any page....
@Inject
private RequestPageCache _cache;
@Inject
private MarkupWriterFactory mwf;
@Inject
private PageRenderInitializer initializer;
public Object doPPR() {
MarkupWriter markupWriter = mwf.newMarkupWriter();
initializer.setup(markupWriter);
Page page = _cache.get("anypage");
ComponentPageElement element =
page.getRootElement().getEmbeddedElement("anycomponent");
RenderQueueImpl queue =
new RenderQueueImpl(page.getLog());
queue.push(element);
queue.run(markupWriter);
initializer.cleanup(markupWriter);
return new
TextStreamResponse("text/html",markupWriter.toString());
}
