Webflow: Dependency injection not working

To answer my question "I don't know if this issue also exists if you don't use a flow.":

No, it doesn't! If no flow is defined in the controller, everything works as expected...

For spring managed beans you could use the following code to load the class (service)...

def ctx = grailsApplication.mainContext
		daoAuthenticationProvider = ctx.getBean("daoAuthenticationProvider", DaoAuthenticationProvider.class)

This tested this issue in 1.1-RC2. It's existing there, too.

I also noticed that also regular controller-properties (not spring-injected properties) are null.

Also existing in 1.1

This is the biggest issue keeping me from upgrading to v1.1, I do NOT want to refactor code only to un-refactor it when you fix this. Please promote this for 1.1.1

fixed in Git master

Thank you!

I have upgraded to grails 1.1.1 but I am still having the same issue with dependency injection from within a flow. I downloaded the example in the attachment, ran a grails upgrade after updating my path to use grails 1.1.1 to update the project. When I do a {{ grails clean }} followed by a {{ grails run-app }} I get the same error as when using grails 1.1, i.e. NPE:

[copy] Copied 2 empty directories to 2 empty directories under /Users/adamkaoullas/.grails/1.1.1/projects/flow_bugreport/resources

Has this issue definitely been resolved for version 1.1.1?

Thanks...

See GRAILS-4299 for continuation of this issue. Workaround is to pass in the service into the method external to the Web flow. See GRAILS-4299 for more info.

Is still not working in grails 1.3.4:

class SomeController {
    def someService

    def someAction = {        
        someService.doSomething() // someService is not null
    }

    def someFlow = {        
        someService.doSomething() // someService is null
    }
}

@Cazacu: this is just working fine for me in Grails 1.3.3/1.3.4. Probably you service itself has some compilation problems? Any difference if you inject it in a typed way e.g. "SomeService someService"?

I've been also working with webflows in Grails 1.3.5, and found the same issue as @cazacu.
I also tried typing the Service and still doesn't work

@cazacu and @eduardo this is NOT the same issue.

The original issue was that, when calling a non-flow action from a flow action, injection would not work.

Your issue is that, in a controller with flow and non-flow actions, the flow actions don't seem to have injected objects. (something I haven't verified).

I would suggest creating a new JIRA for this, as it is a different issue.

Bulk closing bunch of resolved issues

@Graeme Rocher – this is still very broken in 2.1.x
