system.util.setLoggingLevel fail in clien scope

We upgrade an existing application from 7.8.4 to 7.9.0-rc1 (use in dev env)

system.util.setLoggingLevel fail in clien scope.

For example, the following script on a buuton :

import system

generate the error :

Traceback (most recent call last):
File “event:actionPerformed”, line 4, in

ValueError: Unable to change logger level: NameError: The Logger mylogcould not be found.
Ignition v7.9.0-rc1 (b2016091917)
Java: Oracle Corporation 1.8.0_102

Moreover User logger doesn’t appear in 7.9rc1 in the client diagnostics windows as in 7.8.4.

This looks like some sort of regression bug. We’ll get it fixed before final release. Thanks for the heads up!
