Description Andrew Johnson CLA 2010-07-13 12:19:50 EDT 
To reproduce, bring up a histogram, type 'x' into the filter field for class name then click on the class name column heading.

An internal error occurred during: "Sorting...".

Comment 1 Andrew Johnson CLA 2010-07-13 12:20:45 EDT 
There's a simple fix in RefinedResultViewer.resort()
Comment 2 Andrew Johnson CLA 2010-07-13 12:29:23 EDT 
Check for null children in resort()
