I have a component in AEM with a property that's Rich Text enabled using sling:resourceType - cq/gui/components/authoring/dialog/richtext
The component is working correctly in edit mode for Source Edit. The HTML tags render the content enter correctly.
However, as soon as I click ok and come to Edit/Preview screen - The content comes with HTML tags (like <h6>Hello, Rohan</h6>)
So the source edit works correctly when configuring content but the html tags do not get removed in edit/preview mode.
I have attached 3 screenshots showing the same. I can send the xml of the dialog if required. Image 1 - Source Edit ModeImage 2 - Normal Edit Mode outside Source EditImage 3 - Component in Headquarters
What's stripping the custom tags is XSS filter, which is based on OWASP AntiSamy. You can find and customize the configuration for it under /libs/cq/xssprotection/config.xml. There you can add rules to allow your custom tag.
