refreshing MinimWatch with an invalid subnet crashes - winxi - 16-03-2015 20:15
Hi, I recently set up MinimServer in a new network environment and came across the following MinimWatch crash:
1) Start MinimWatch with an invalid ohnet.subnet property set. MinimWatch will show the red icon with a 'subnet not found'- message, as expected.
2) Click 'Refresh'. MinimWatch will crash with a NullPointerException.

Thanks for letting me know. Can you post the full stack trace (available in the log window)?

This problem is now fixed in MinimWatch update 31. There are two changes:
1) Fix NullPointerException when Refresh is selected and ohNet hasn't been started
2) Show Relaunch instead of Refresh after a startup error
Thanks for helping me find and fix this problem!
