Intro

There is a case that fileReference is set as an array in the JCR.

This happens when there is an image, which already has an asset set, editing it, clearing the reference and setting a new image.

Reproduction

• Setup a new AEM 6.5 author on port 4502

• Create a sample project using wcm.io archetype

  • https://wcm.io/tooling/maven/archetypes/aem/usage.html

  • Using example from "AEM project with wcm.io and Sling-Initial-Content project layout and Java 11"

     

• Install the sample project “./build-deploy.sh”

• Open http://localhost:4502/editor.html/content/myproject1/en.html

• Add an image component, set an image, save

• Edit that component, press “Clear”, save

• Edit that component, set an image, save

• Open http://localhost:4502/crx/de/index.jsp#/content/myproject1/en/jcr%3Acontent/root/content/image

Actual behavior

Expected behavior

Side note

• I tried the Adobe core component:

  • http://localhost:4502/crx/de/index.jsp#/apps/myproject1/core/components/content/image

  • set sling:resourceSuperType to core/wcm/components/image/v2/image

• The problem does not occur
