I wanted to use the the ACS AEM Commons composite multi field in the Touch UI in metadata editor and the widget is getting rendered in the metadata editor for an asset but when I try to edit it, it throws error.
Only if I add the /jcr:content/metadata to the properties name , I am able to post the data to AEM. But rendering of the Touchfield does not happen since the values are getting stored in the metadata node as array of values for each property.
