Form core components breaks AEM core components implementation

[koffieislekker]

I have an AEM project that already installs the aem core components (2.22.12). I am not sure why the forms core components also embedds the aem core components (which I think causes the issue) since this can be installed/seperatly in your project pom.xml

Expected Behaviour

When trying to extend the AEM core components I expect the core component to be able to be injected properly.

Actual Behaviour

When installing the forms core component the aem sites project that extend an AEM core component breaks.

Reproduce Scenario (including but not limited to)

Adding a simple List implementation java class that injects the Core components List component breaks the component.

Steps to Reproduce

1. Create a project
   mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate -D archetypeGroupId=com.adobe.aem -D archetypeArtifactId=aem-project-archetype -D archetypeVersion=43 -D appTitle="My Site" -D appId="mysite" -D groupId="com.mysite" -D aemVersion=6.5.17 -D includeExamples=y -D includeFormscommunications=y -D includeFormsenrollment=y

2. Create a simple List class (Could be any core component class)

3. Go to the generated en.html (project must be built first) and add the List component to the page.

Platform and Version

Windows 11
Java 11.0.19

AEM Version (mention the exact version in case of cloud SDK)

AEM 6.5.17

AEM Forms Version

adobe-aemfd-win-pkg-6.0.968

Sample Code that illustrates the problem

package com.mysite.core.models;

@model(adaptables = SlingHttpServletRequest.class, adapters = {List.class}, resourceType =
MyCustomListImpl.RESOURCE_TYPE)
public class MyCustomListImpl implements List {

protected static final String RESOURCE_TYPE = "mysite/components/list";

@Self
@Via(type = ResourceSuperType.class)
private List list;

@Override
public Collection<ListItem> getListItems() {
    return list.getListItems();
}

}

@koffieislekker did this ever get solved or did you create an adobe support ticket for this?

[barshat7]

@koffieislekker Can you try with the latest version for 6.5? It should be fixed in the 1.3.2 version

[rismehta]

@royteeuwen @koffieislekker I have created a hotfix for this over 6.5.17, https://github.com/adobe/aem-core-forms-components/releases/tag/core-forms-components-reactor-1.1.27-wcmB004.

Kindly verify whether this hotfix resolves the problem.
