SmartDashboard Crash

[origamitaco]

Sorry I should have checked this sooner. I ended up deleting wpilib folder containing smartdashboard.jar and redownloaded the plugins in eclipse. Worked like a charm but I did have to rearrange the dashboard layout. I'll remember this for future reference though, thanks.

Hello, I am having the same issue where as soon as you launch the driver station and the smartdashboard loads, it crashes. I have tried reinstalling the c++ toolchain, and the deleting the eclipse plugins and reinstalling them.

Here are the logs from running Joe's suggestions

Java version:

C:\Users\tigertronics>java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

running smartdashboard from cmd:

C:\Users\tigertronics>java -jar C:\users\tigertronics\wpilib\tools\smartdashboar

Any suggestions?

Alright, I figured it out. The reason the smartdashboard crashes is because you are using an old dashboard save from last year. To fix this just navigate to:

C:\Users\"user"\SmartDashboard

and delete save.xml.

Then it should work,. However, I ran into another issue when formatting different values on the smartdashboard. Whenever I try to change a simple text box to a line plot or simple dial, the value disappears and does not show up again until you reboot the dashboard. When it does reappear, it is just in a text box again.

If anyone can reproduce this issue or has suggestions, please respond.

I duplicated the problem and submitted a patch for review.

any idea when the patch will come out as part of an update?
