Description Kevin Haaland CLA 2001-10-10 22:33:08 EDT 
When you undo something, the undo action is performed but the position at which the
	operation occurred is not made visible in the active editor view.

	To reproduce:
	Double-click on a (fairly large) *.java resource to open an editor view.
	Make some changes spread throughout the file on distict visible screen "pages".
	Hit undo (Ctrl-Z, context-menu or menuitem) several times.
	Note that though the changes have been undone, the editor view was not
		scrolled to each change as it was undone.  It may be difficult to see that the changes
		were undone as there was no visual confirmation that the undo action took place.

This is not an enhancement, but a required feature of any editor.
I think you should promote it's severity.
Comment 7 Genady Beryozkin CLA 2002-03-11 01:35:18 EST 
the problem is in SWT's StyledText class.
see last line of StyledText.replaceTextRange() which is used by undo functions.
the argument is always false.
Probably two overloaded methods are needed to allow to specify that argument.
