Confluence is a Java based, enterprisey WIKI that is built using the precursor to Struts 2. So I consider it newsworthy when someone takes the time to write about extending Confluence with the best web technology currently available: Apache Wicket. Gustavo explains how to do just so:
The advantage would be avoiding completely XWork, possibility to use wicket advanced features and possibility to run the feature outside confluence (more testable).
Thanks for the write up, Gustavo!
