Stian Thorgersen commented on AS7-3177:
---------------------------------------
The stack trace was from my actual application, sorry for not attaching a fresh one for the test case (which I should have created prior to creating the issue!)
I agree with the fact that this may not be supposed to work (how would you for instance chose which method to use if there are multiple overloaded methods, so it may in fact be dangerous to allow this). However, it used to work in 7.0.1/7.0.2.
I've got a work around at the moment, duplicated the commandLinks, created methods without parameters, etc. not pretty, but does the job. Would certainly be much cleaner if it works passing a null.

> I have a web app that works in 7.0.2.Final, but doesn't work in 7.1.0.CR1b. The problem seems to be that method expression parameters no longer works. When trying to invoke a method with parameters the following exception is thrown:
