I have installed AEM 6.0 quickstart, and also installed the example described here:
I am able to open the adaptive form for edit, however the adaptive form data model tab (on left hand side) is blank, screenshot attached. Also, there is a warning: "Unable to generate JSON from Template provided in Adaptive Form. Please see the server logs for more Information".
I couldn't find further information in the logs.
Has anyone had issues using the sample adaptive form described in the link above?
Can you post the error.log file for time when you open the authoring?
Are open to render the XDP Form Template as Mobile Form independently of the adaptive form using AEM form UI?
