URL: http://issues.apache.org/struts/browse/SHALE-268
Project: Shale
Issue Type: Improvement
Components: Dialog
Affects Versions: 1.0.3

It should be possible to register listeners against dialog execution so the
application can take whatever action it needs, either on failure, or routine
progress (entry/exit etc.)
