Lance updated TAP5-1864:
------------------------

    Comment: was deleted

(was: Something like this:

{code}
package foo.bar.components;

public class CaptureBody {
   @Property
   private Binding value;

   @Property
   private MarkupHandler handler;

   void beforeRender(MarkupWriter writer) {
      if (value == null && handler == null) {
         throw new IllegalStateException("value or handler must be specified");
      }
      writer.element("deleteme");
   }

   // let the body render

   void afterRender(MarkupWriter writer) {
      Element container = writer.getElement();
      writer.end();
      String markup = container.getChildMarkup();
      container.remove();

      if (value != null) {
         value.set(markup);
      }

      if (handler != null) {
         handler.handle(markup);
      }
   }
}
{code})

> I've seen several posts on the mailing lists asking for how to render blocks manually
in pages/components.
> Had a use case in this issue: https://issues.apache.org/jira/browse/TAP5-1863
> Basically I tried with:
> -------- 
> RenderCommand renderCommand = (RenderCommand)alertBlock; 
> MarkupWriter markupWriter = new MarkupWriterImpl(); 
> RenderQueueImpl renderQueue = new RenderQueueImpl(log); 
> renderQueue.push(renderCommand); 
> renderQueue.run(markupWriter); 
> alertManager.info(markupWriter.toString()); 
> -------- 
> Don't know if it's the 'correct' way of doing things so requesting a service or a helper
class available in core that does the job.
