Problems with SmartDashboardFX (SFX)

[gbear605]

I have two independent problems with SFX. First: I cannot get my plugin (https://github.com/Nashoba-Robotics/CoffinLED) to work. The log is

Using Java 1.8.0_25-b17 and JRuby 1.7.23
Release/Built? true Version Identifier: jenkins-SFX-42-42-c6c3c5118c391af8bd0faf54c9713f8e89806c6e
Exception in thread "JavaFX Application Thread" org.jruby.exceptions.RaiseException: (NoMethodError) undefined method `gsub' for nil:NilClass

This only happens when my plugin is in the plugins folder, so it is clearly an issue with it. However, I can't tell what is causing the issue, since I'm not calling any gsub method.

The second problem is more generic: When I attempt to follow http://wpilib.screenstepslive.com/s/4485/m/26401/l/255410-setting-sfx-to-launch-with-the-ds, it doesn't work, but when I follow the trouble shooting steps, they have no issues.

Thanks for any help
