HI, I am learning struts 2 with Tiles 2 and the word "topic" shows up very frequently... What is a topic?
for example:
The sx:a tag (specifically the ajax a template) and the div tag support an ajax event system, providing the ability to broadcast events to topics. You can specify the topics to listen to using a comma separated list in the listenTopics attribute. What this means is that when a topic is published, usually through the ajax a template, the URL specified in the href attribute will be re-requested.
