Actions now require INPUT result after installing struts2-spring plugin

Question

I've recently installed the struts2-spring plugin and everything seems to be working as expected from the Spring perspective; however, Struts actions now require an "input" result to be defined when there was not one before.

I have no idea why this is the case, but I would rather not go through my many actions defining dummy input results when they're not being used.

What I've verified:

• Spring context is being started up
• If there is an "input" result to the action, @Autowire is correctly autowiring the Spring beans into non-spring Actions.
  What I think is the next clue, but I'm not sure why or where to go from here:

03:34:37,651 DEBUG
[org.apache.struts2.interceptor.validation.AnnotationValidationInterceptor] (http--0.0.0.0-8443-5) Validating //ftli with method execute.

^^ Is this line saying that the Action is being validated and then it's forwarding to "input" afterward?

Example Action where this fails:

${file}

I appreciate any suggestions or direction from here.

Comments

Without further info it's difficult to help. Sounds like validation or type conversion is failing.

Unfortunately, I don't really have much more information to go on. What other information might be helpful to debug this? This is Struts 2.3.15 and Spring 3.2.3

Just the things noted in this document:

http://struts.apache.org/release/2.0.x/docs/spring-plugin.html

and you know what, that's the evil of google, I just noticed (while googling from home) that this is the appropriate doc:

http://struts.apache.org/release/2.3.x/docs/spring-plugin.html

I'm assuming this is my problem.
