Description aekold 2009-07-28 13:01:24 UTC

Product Version: NetBeans IDE 6.7 (Build 200906241340)
Java: 1.6.0_14; Java HotSpot(TM) Client VM 14.0-b16
System: Windows XP version 5.1 running on x86; Cp1251; ru_RU (nb)
Userdir: D:\develop\labs\nbprofile67

All folding checkboxes in preferences are checked. When document folded and I am unfolding one section and using it as 
example to write another similar section - with any document structure change manually unfolded block folds back, and I 
have to unfold it once again.

Steps to reproduce:
(I am using line numbers from attached file)
1. Check all folding checkboxes in preferences.
2. Open build-impl.xml (from attachment or any of your projects).
3. Unfold block at line 678 and all it's subblocks.
3. Go to line 685
4. After line 685 start typing another <target

Expected result: block at line 678 will stay unfolded if it was unfolded manyally
Actual result: block at line 678 folded back, manual unfolding required to see it again.

IMO this is a problem in XML fold manager, which always creates new folds instead of reusing existing ones. The
infrastructure applies the folding rules to any newly created fold.
