adding listener to StaticEventBus throws "Argument count mismatch" error on listener function

[Yennick Trevels]

When adding an eventListener on the StaticEventBus I immediately get an "Argument count mismatch" error because the logger is trying to call the listener function.

I'm using:

• commons-logging 2.7
• commons-eventbus 1.4.0
• Flex 4.5

This is the stacktrace:

ArgumentError: Error #1063: Argument count mismatch on MainTest/eventBus_loggedInHandler(). Expected 1, got 3.

I also created a small testcase which reproduces the error:

Anyone has an idea why this is going wrong?

Thanks.

This seems to be an issue with the FlexLogTarget, have you tried just using the TraceTarget like this?

LOGGER_FACTORY.setup = new SimpleTargetSetup(new TraceTarget());

I personally never use the Flex logger, so I never ran into the issue, apparently the Flex logger can't
take a Function argument, I've looked ta the code briefly but I can't figure out why its actually
invoking the function.

[Yennick Trevels]

No, didn't try that before. Wish I did because it works ;) Thanks!

It was also a mystery to me why it was calling the function when looking at the source code.
