icegridadmin java backtrace

[ctennis]

Here's another backtrace I've gotten when playing around with the icegridadmin GUI. I don't know what I did specifically to cause it to happen; I just noticed it.

The program continues to run just fine and I haven't noticed any side effects, so it may just be a minor issue.

java.lang.NullPointerException

Hi Caleb,

This shows an attempt to save an application to an IceGrid registry while you're not connected to any registry.

Naturally, this should never happen: the corresponding menu / button should only be active when you're connected. And if you loose the connection while saving to the registry, you should not get a NullPointerException.

Thanks for the bug report!
