Hi, 
We are using OOTB ca-config "com.adobe.cq.wcm.core.components.config.HtmlPageItemsConfig" to load a script on our page.
But the script src is different for each environment. So, to override it through OSGI, I have tried using Apache Sling Context-Aware Configuration Override Provider: OSGi configuration. 
my Ca-config is stored as follows:

Hi,

 

I think there’s some confusion, or perhaps I misunderstood your use case. If you need to switch a script per environment, you should use run modes and environment variables, as this is a more flexible and scalable approach. Context-Aware configurations are intended for multi-tenant projects within the same environment. Please check these threads:

Hope this helps

    Hi Esteban,

    yes, I am aware of run modes, we are using ca-configs and few ca-configs have "src" values of which are run mode specific so I am trying to override the src of ca-configs through OSGI via Apache caconfig override provider.

      Hi @arunpatidar,

      Thanks for your response!
      I have tried the way you have mentioned, syntax issue is solved but I am unable to override the property.
      In general if you look at any ca-config, the properties are stored under jcr:content node, but for this config it is stored in the child resources present under jcr:node, this is causing some issue in identifying the property. is there a way to point the property for such configurations?

      Hi @rahulga6 
      By providing an implementation of org.apache.sling.caconfig.spi.ConfigurationOverrideProvider you can provide your own overrides - if the built-in override providers do not fit your needs.

      https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configuration-override.html 

      Example : https://github.com/wcm-io/io.wcm.caconfig.extensions/blob/master/src/main/java/io/wcm/caconfig/extensions/override/impl/RequestHeaderConfigurationOverrideProvider.java 

      https://github.com/headwirecom/sling/tree/bc84670463a87c6e9c606ba286efc7dbf4dd70c7/bundles/extensions/caconfig/impl/src/main/java/org/apache/sling/caconfig/impl/override
