Anybody recognized the "error on page" message when configuring a filter
with imanager, that contains a network as source address?
I was able to reproduce it on several systems.

use iManager 2.0.2 (even with the latest patches) and bm3.8(4).
When you configure an exception that contains a Network as source address
you cant go to the "next" page.

I tried with browser set to german and english as well.
