Affects Version/s: 7.0.X, 7.1.X
1. Set up a latest master and add to the portal-ext.properties the following property then start it:
2. Go to Content --> Web Content and create a basic web content.
3. Click on the 3 dots beside the content and select "Edit"
4. Change the content and leave the Summary empty then click on "Preview" from the upper right 3 dots.
Actual Behavior: Error appears: web content is temporarily unavailable. NullPointerException in the logs.
Expected Behavior: A pop up window should appear with the option to save the new content and after saving it, the preview of the edited content appears.
7.1.x @ cc834f237de2d6e0b223e973f5d3f35349eb5c37
Master @ bcca1cda3713d8a75b7bfb0ddd7503d9efcdab5b
Note: On 7.1.x there's no error. However, the ckeditor field seems to be insensitive to changes: preview shows the old version of the text, without asking whether to save it as a draft. Works correctly when e.g. Summary is changed.
