RC3 (with fix for bug 139593 applied) Use the following program: public class Strings { public static void main(String[] args) { String[] strings = new String[1000]; strings[0] = "a"; strings[1] = "b"; System.out.println("over over"); // breakpoint here } } * debug to the breakpoint * open the expressions view * add 'strings' as an expression * expand the second range 100...199 * expand the first range 0...99 * debug another program to a breakpoint * select its stack frame (that does not have a variable named 'strings') * expression view left in wierd state

Appears to that the view scrolls to make the "error message" node not visible. Since it is not visible, it does not get a 'set data' callback when the tree is cleared, and it does not force its children to refresh. Once scrolled into view, the children are properly updated. Can reproduce with SWT example: /******************************************************************************* * Copyright (c) 2006 IBM Corporation and others. * All rights reserved.

This works with the fix to bug 143805 *** This bug has been marked as a duplicate of 143805 ***
