How do you open the page? aren't you creating a new object each time instead opening the edit-page of an existing object?
Hi,
When you try to open the record which is already saved. Then value will come for sure.Can you share any screenshots for more information.
Here is comes some screen dumps;
And when I run the application I press save and the value is saved in the entity but when I open the page again nothing is checked!?
I highly recommend you follow some of the free online learning. The Rapid Developer course covers these concepts and the other basics you’ll need to get a smooth start on the platform:
