Sling Model error, not injecting property

[bfvaughn]

Here is the warning...

08.11.2017 08:46:03.433 *WARN*

org.apache.sling.models.impl.injectors.ResourcePathInjector Could not retrieve resource at path NOT_SELECTED for field bottomMargin. Since it is required it won't be injected.

here is the groovy code:

@Component(value="Thumbnail",tabs = [@Tab(title = "General"), @Tab(title = "Advanced"), @Tab(title = "Override")],group="Basic")

@Model(adaptables=Resource,defaultInjectionStrategy=DefaultInjectionStrategy.OPTIONAL)

@Slf4j
class Thumbnail implements BottomMargin {

....

@Inject
Margin bottomMargin

...

}

Margin is an enum and NOT_SELECTED is the correct value.

For starters - here you are using @Component and @Model annotations.

Check this doc - @Component is not a sling model annotation-  never seen them used together - not sure if that is valid.,

Apache Sling :: Sling Models

2nd - looks like you are trying to use Sling Model to inject node/props - this message indicates that the resource cannot be found at the JCR location.

"Could not retrieve resource at path"

If you want to use JCR node/props and inject them into data members with the @inject annotation - make sure that the nodes are part of the JCR location. See this example --

Scott's Digital Community: Creating Adobe Experience Manager 6.3 Sling Model Components

We successfully inject JCR node properties using @inject.  You can get a resource on which to base the sling model like this:

Resource resource = resolver.getResource("/content/testsling/slingmodel");

Hope this helps....

Sorry, I should have included the imports:

import com.citytechinc.cq.component.annotations.Component

import org.apache.sling.models.annotations.Model

So the wierd part is that NOT_SELECTED is the value for the property bottomMargin.

The property bottomMargin in an enum defined below.

public enum Margin {

   @Option(text = "Not Selected")

   NOT_SELECTED("")

  private String cssClass;

  private Margin(String cssClass) {

   this.cssClass = cssClass;

  }

}

Are you trying to bind part of your model to JCR nodes located in the repository?

This simply means that there is no property/resource called "NOT_SELECTED".
