Having multiple nested methods with the same name inside the same method is not a scenario we support (or want to support).

Carlo,
The nested methods with the same name are in different methods.
Have you wanted to say within the same class?
This would work perfectly in Delphi.
The strange thing is that if the constructor is not virtual everything works perfectly, however, if the constructor is virtual or there is a defined “class of” of this class then and only then does not work.
Please look at the video for a better understanding.

Thanks Carlo.

Carlo,
In version 8.4.96.2019 this error was fixed, however, in the latest version 8.3.94.2021 this error reappears.
Best regards,
Jose A.

Yes. 8.3 is an old branch, up for release soon. 8.4 is the beta.

10

We thought that the only difference between betas 8.3 and 8.4 was support Island and Gotham, but errors were fixed in both branches.

11

Some other stuff was also done in the betas only, especially when it had far reaching code changes.

12

Then, for error fixes, we just have to download the 8.4 branch?

13

Yes. You need the 8.4 branch for these fixes.
