Opening a sheet on the Display causes a NullPointerException
------------------------------------------------------------
Key: PIVOT-162
URL: https://issues.apache.org/jira/browse/PIVOT-162
Project: Pivot
Issue Type: Bug
Components: wtk
Reporter: Todd Volkert
Assignee: Greg Brown
Fix For: 1.3
Sheet has an open(Display) override, so it looks like we try to support this
case, but if you do it, you get an exception. What's worse is that if you get
this exception in your startup method, then you can't close the host frame
using the close button - you have to kill the Java process.
