Karol Lewandowski reopened SLING-12302:
---------------------------------------
> CA Config access syntax is inconsistent in HTL
> ----------------------------------------------
>
> Key: SLING-12302
> URL: https://issues.apache.org/jira/browse/SLING-12302
> Project: Sling
> Issue Type: Bug
> Reporter: Karol Lewandowski
> Assignee: Stefan Seifert
> Priority: Major
>
> I have a problem understanding how nested configs can be accessed in HTL or
> if there is a bug in the implementation.
> The
> [documentation|https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configuration.html#accessing-configuration-from-htlsightly-templates]
> gives an example:
> {{{}$\{caconfig['x.y.z.ConfigSample']['nestedConfig/stringParam']{}}}}
> However, it doesn't work when a configuration annotation class is defined.
> Steps to reproduce:
> 1. Create a config node:
> {{/conf/we-retail/sling:configs/us/en/sling:configs/com.mysite.core.config.TestConfig}}
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0";
> xmlns:jcr="http://www.jcp.org/jcr/1.0";
> jcr:primaryType="sling:OsgiConfig"
> email="t...@example.com"
> enabled="{Boolean}true"
> number="{Long}123">
> <nested
> jcr:primaryType="sling:OsgiConfig"
> greeting="hello"/>
> </jcr:root>
> {code}
> and reference it from some path.
> 2. Access in HTL without configuration annotation class:
> {code}
> Email: ${caconfig['com.mysite.core.config.TestConfig'].email}
> Number: ${caconfig['com.mysite.core.config.TestConfig'].number}
> Enabled: ${caconfig['com.mysite.core.config.TestConfig'].enabled}
> Greeting (config path):
> ${caconfig['com.mysite.core.config.TestConfig/nested'].greeting}
> Greeting (property path):
> ${caconfig['com.mysite.core.config.TestConfig']['nested/greeting']} {code}
> This gives the output:
> {code}
> Email: t...@example.com
> Number: 123
> Enabled: true
> Greeting (config path): hello
> Greeting (property path): hello {code}
> It works as expected.
> 3. Create annotation classes:
> {code:java}
> package com.mysite.core.config;
> import org.apache.sling.caconfig.annotation.Configuration;
> @Configuration
> public @interface TestConfig {
> String email();
> int number() default 5;
> boolean enabled();
> NestedConfig nested();
> }
> {code}
> and
> {code:java}
> package com.mysite.core.config;
> public @interface NestedConfig {
> String greeting();
> }
> {code}
> The previous HTL will print:
> {code}
> Email: t...@example.com
> Number: 123
> Enabled: true
> Greeting (config path): hello
> Greeting (property path): {code}
> Accessing nested config value with property name path doesn't work. Is it
> expected?
> I'm working on support for CA Configs in AEM IDE, so I don't want to make it
> work in my AEM application but provide the correct syntax support.
