NPE (near) Select Tables to Graph dialog

I'm not able to replicate the exact steps, and I'm not sure how the exception happened. But it had something to do with the graphs, and selecting selected tables to show. An internal error occurred in: java.lang.NullPointerException The error may have affected the application state. Please to vendor.
