We use the Angular + Code version (6.9.1)
When we create a page with the PowerTool there are errors with the modals. The main problem is that you display the modal only with "show" and "hide" and replace the data.
The modal should always be completely reloaded when editing an entry.
Examples of errors:
I have an error message when validating a field. I close the modal without saving and open another entry. All error messages are immediately visible although I haven't changed anything in the new entry yet.
I have readonly fields depending on the settings for some entries. If I edit an entry and the fields become readonly then they remain readonly for every entry I open afterwards.
We've changed that for us, but you might want to change it for you too to make it effective for everyone?
