I have started using Liferay 7 on Wildfly. I successfully created a Form and then added this Form to a webpage. I then created a second Form, but I couldn't add it to a page. The ajax timer just turns a few times and then nothing - the page remains unchanged. I then deleted the Form and tried to add my first Form - nothing. I deleted the first Form and still cant get the Form add to work. I tried restarting the portal, validating the DB tables, all without success.
