NetConfig wont load after changes

[nirmal singh]

Hi Team,

I am new to cloverleaf so have limited knowledge.

So today after making changes to the Netconfig( adding new java thread ) when I saved the network config, it starting giving errors and when I closed the IDE and opened it again it wont open gave error as “Process already running”. So we had to restart the cloverleaf service. After that no its giving error as: “Fail to initialize main panel.” and below is the stacktrace :

Look in your revisions folder and go back to a NetConfig version that was working.

We are on a UNIX platform, so I don’t know if this helps you.

Thank you Mary Kobis, that worked just fine.

No problem, glad to help! I was panic stricken the first time it happened to me!  😯
