override Context-Aware Configuration (CAConfig) values at the page level

Hi @nehaba4,

To override CAConfig values at the page level while still falling back to parent-level defaults, follow this hybrid approach:

Step 1: Enable CAConfig at Page Level

Ensure your page components or templates allow CAConfig to resolve from the page itself by using:

config = contextAwareConfig.resource().adaptTo(YourSEOConfig.class);

AEM will automatically walk up the content hierarchy (/content/page-x, /content/brand-x, etc.) until it finds a config node.

Step 2: Use Overlaying via /jcr:content/.config

You can override config at the page level by allowing authors to define a hidden configuration node:

/content/brand-x/page-x/jcr:content/.config/com.yourproject.config.SEOConfig

Populate only the properties you want to override - eg. just og:title.

Step 3: Use a Wrapper Sling Model to Merge Configs

Create a wrapper model that merges page-level and brand-level configs:

@Model(adaptables = Resource.class)
public class MergedSEOConfig {

    @Inject @Via("resource")
    @Optional
    private SEOConfig currentPageConfig;

    @Inject
    @Via("resource")
    @DefaultInjectionStrategy(OPTIONAL)
    private ConfigurationBuilder configBuilder;

    public String getOgTitle() {
        if (currentPageConfig != null && StringUtils.isNotBlank(currentPageConfig.ogTitle())) {
            return currentPageConfig.ogTitle();
        }
        return configBuilder.name("com.yourproject.config.SEOConfig").as(SEOConfig.class).ogTitle();
    }

    // Add other fields similarly...
}
