Re: Rendering block from Java

Since 5.4, Tapestry has the PartialTemplateRenderer service, which renders
different objects and returns them as a String:
http://tapestry.apache.org/5.4/apidocs/org/apache/tapestry5/services/PartialTemplateRenderer.html
.

Example:
https://github.com/apache/tapestry-5/blob/master/tapestry-core/src/test/java/org/apache/tapestry5/integration/app1/pages/PartialTemplateRendererDemo.java
https://github.com/apache/tapestry-5/blob/master/tapestry-core/src/test/app1/PartialTemplateRendererDemo.tml
