Solved
Are event properties like resourceAddedAttributes and resourceChangedAttributes no longer supported in AEM 6.3?
We have a listener that's failing on us that has a filter that has filters like this.
(resourceType=ourOurg/components/content/ourComponent)
(resourceChangedAttributes=ctaPath)
(path=/content/*)
What's happening is that the event isn't firing. When I remove these filters and leave behind the path filter the event fires, but when I debug it it's missing those properties.
