Description Remy Suen CLA 2011-07-14 09:04:12 EDT 
1. Open the 'XPath' view.
2. Create a DTD file.
3. An exception will occur after the editor opens.

At this point, either the active stack will no longer be updated. Ctrl+W may work, but it will stop working when you reopen the editor. Using a new window seems to work but the active stack colouring is still not present.

Comment 1 Remy Suen CLA 2011-07-14 09:17:41 EDT 
There seems to be a bug downstream as the same steps will produce an error although the line numbers are not identical. See bug 352079.
Comment 2 Remy Suen CLA 2011-07-14 12:39:17 EDT 
Fixed by commit d0b509b6b285dcdd425996f0bacfd76d5fcacd81 in R4_development.
