[IDV #HYJ-820832]: Persistent Java errors in the Surface (METAR) Data layer

Dear Marsh,

I was able to fix your bundle with the following steps:

Open the broken AtlanticRegion.xidv bundle.

Go to the layout model for METARS (in the same fashion as you did when you 
tried to change the unit to Celsius). You can still do this even though the 
bundle is broken.

The layout model is accessible via the Dashboard, Display tab. Go to the 
Surface (METAR) Data view. Go to Edit --> Layout Model.

Temporarily change the layout model unit back to Fahrenheit.

This should revive the bundle.

Once you have confirmed the bundle is working again, please switch back to the 
desired unit. Note the Celsius unit is available from the unit drop down list 
in the layout model.

Save the fixed bundle.

Keep us up-to-date on your progress.

Best Wishes,

Unidata IDV Support
