Are you an Applied Biosystems (ABI) 3500 Series user running into a frustrating error when trying to set up your sequencing run? You're not alone. We've seen an issue pop up where the software throws a "Could not create the view: An unexpected exception was thrown, java.lang.NullPointerException" error specifically when generating the 'Load Plates for Run' page.
