How to debug the "error Alert may not be null"?

[scarfagna72 (Stefano Carfagna)]

After upgrading a test project from 2.2.0 to 2.3.0
Deleting DB
Recreating DB
i got the error "How to debug the “error Alert may not be null” ?
on each Entity detail editor.
Is there a way to debug the issue ?
regards
Stefano

Hi

1. Navigate to Notifications class
2. Set breakpoints to it’s methods
3. Reproduce the problem and check the stack

I’m going to try.

Does this view shows all attributes of the entity? Maybe there are some hidden ones annotated with @NotNull?

My entity was being setup programmatically mainly and I was facing same issue. I got null property name by putting breakpoint in BeanValidationListener.validateOnCallbackEvent method.
