A-pZ commented on WW-3997:
--------------------------
I had a same problem.
An empty action ( at convention plugin : Action(value="") ) don't work and
response 404(FileNotFound) since version 2.3.10.
I thought this problem maybe changed
DefaultActionMapper(org.apache.struts2.dispatcher.mapper.DefaultActionMapper) ,
exactly DefaultActionMapper#getMapping() was return null at action that set
blank string.
Version 2.3.12 DefaultActionMapper#getMapping at line 316 is here.
if (StringUtils.isEmpty(mapping.getName())) { ......
Version 2.3.8 is here.
if (mapping.getName() == null) { ......
Is it necessary to change by other issue?
