Spring framework and abstract method question
Hello,
In my component class I have:
public abstract ManagerUserImpl getUserService();
When I request the tapestry servlet, I get the
exception:
Method "setUserService" failed for object.
There was no set method in the docs at:
http://www.springframework.org/docs/reference/view.html#view-tapestry-context
Is it still valid to just implement one of the two
accessors?
Thanks,
Lance

Re: Spring framework and abstract method question

It seems to be a property type problem.
In your page specification, the userService property type has to be
"UserService":
<property-specification name="userService"
type="com.whatever.services.service.user.UserService">
global.appContext.getBean("userService")
</property-specification>
and in your page class, the abstract method has to return an UserService:
public abstract UserService getUserService();
If you has renamed the UserService to ManagerUser, you property has to be
of type ManagerUser, not ManagerUserImpl.

Julio

The java class only needs to declare the getter or setters you actually
need to use from your code. If you are not going to use a setter, you
don't have to declare the abstract stub for it. The enhanced class will
still have it of course.
What specific error are you getting? I think the set is probably not
failing, but rather, what is failing is getting a valid value to set...
