This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
If a read only file (such as a .java) is opened in the code editor, and this file is then made writeable on the filesystem, although the file becomes editable in the code editor, the grey background remains. The file needs to be closed and reopened in the code editor before the background turns white. Product Version = NetBeans IDE 6.9 (Build 201006101454) Operating System = Windows XP version 5.1 running on x86 Java; VM; Vendor = 1.6.0_10 Runtime = Java HotSpot(TM) Client VM 11.0-b15
Moving to editor. As far as I know the title of the editor changes appropriately, so the notification from filesystems to editor is OK. It would be up to editor to adjust the background then.
