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.
How to reproduce: Mount some VCS file system which is in "/tmp/vcs". Its name will be "VCS /tmp/vcs". Exit NB Delete "/tmp/vcs" directory. Start NB OK - Error dialog is shown. ERROR - All actions on VCS file systems are enabled (also New action). Name of VCS file system is still "VCS /tmp/vcs". So valid and invalid VCS file systems are not distinguished. Solution: Change name of invalid VCS file system node similarly to local file system (for example: "Invalid VCS /tmp/vcs")
UI keyword added.
Set target milestone to TBD
Actually fixed in 4.0, the filesystem is not visible anywhere but in Versioning Manager. It's not invalidated.
