Thanks for the reply, Jeromy. That is exactly what has not been working.
Unfortunately, the s:property does not work either.
"dept" is a Department domain object, with two field, deptId: short; and
deptName: String. Both have getters and setters.
The DepartmentAction retrieves the dept object from DB, and has getters and
setters for the domain "dept" object in the action.
I tried:
<s:property value="dept.deptId" />
<s:property value="%{dept.deptId}" />
(as well as a bunch of other things which shouldn't work, and don't)
But this does not work, and I think it should, from what the documentation
says. I can see the Action and the "dept" object on the stack in the Eclipse
debugger. When I created a deptId var, and create a getter and setter for it
in the Action, and do this:
<s:property value="deptId" />
This works just fine, but I shouldn't have to break the domain object out in
the Action, right?
(I don't have a struts.properties file set up, 'cause the default as you
said is enabled.)
This is all fundamental to struts2, so I've got to be doing something
stupid, right?
thanks, shadman
