Hi

without your code, I can only guess, but it looks like...

The error message explains your problem. The variable is FINAL (ie can be set once only and is then immutable). Your code must be trying to reset it.

It is a long time since I did that module, but I think the name was set in the constructor. It is not possible to change it after that without removing the 'final' declaration from the variable
