Hummm… I couldn’t reproduce it in a blank panel too… Maybe it was due to too much forms? Or too much packages? Or due to having forms as modules (currently possible to edit, but not to change in the new editor).
I made a clone of my app where this happens every time I test. Here’s the clone:
And here are the steps for it:
- In the Client Code, go to Components > Commons and create a new Blank Form inside of it;
- Click on Configure Component in this new form.
- Add a property. As soon as you change the property to Form the app shows an error.
