It is enabled. Other ways to invoke methods do work, like a parameter with 
'method:' or adding !method to the URL. The test project is based on this:

https://github.com/lukaszlenart/struts2-convention.git


Things that I changed:
- added a member 'String text' to HelloAction, along with getter/setter
- added a method 'doSave' to HelloAction, which also uses SUCCESS result 
but adds an ActionMessage
- added textfield 'name=text' to hello.jsp
- added button to hello.jsp and played with different action="" and 
method="" attributes

For example <s:submit method="doSave" /> does what expected (invokes 
HelloAction.doSave()).
But <s:submit action="hello!doSave" /> does not (invokes 
HelloAction.execute()).

Christoph
