SmartDashboard Crash

[origamitaco]

SmartDashboard crashes immediately when running Driver Station or when starting from Eclipse. Deleted default save, didn't fix anything. Don't know where to find logfile for crash. Running new 2016 FRC update and WPIlib.

Run SmartDashboard from the command-line and post the output.

java -jar C:\users\<user>\wpilib\tools\smartdashboard.jar

What version of java are you using? Post the output of

java -version

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?

Thanks

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?

It is in yesterday's update.

This may be a silly question, but how do I get the latest update of smart dashboard? I came across this discussion as our team also ran into line plot issue. And firstforge website doesn't seem to be available anymore. I tried teamforge, but couldn't find the installation files. Thanks

Ditto on that nhchen. We're running into the same issue with the lineplot and compass widgets disappearing. And we haven't necessarily found the latest update of smart dashboard.
