The code to reproduce: Module 1.bugreport.zip (1.4 MB)
The build log: Module 1.bugreport.txt (32.3 KB)
When you wire an event from an aspect, it looks for a method with 0 parameters (that does not exist), causing the error
No overloaded method "MyEventHandler" with 0 parameters on type "Test"
Followed by the hint:
Best matching overload is "MyEventHandler(p: String)"
The one mentioned in the hint IS the one that was assigned as eventhandler.
