Occasionally when you click to expand a folder, eg 'Models', navigator somehow thinks the folder is empty when it isn't, so it doesn't expand it. The Files manager still works correctly. The problem persists until Netbeans is restarted or the project re-opened. Product Version = NetBeans IDE 7.0 Beta (Build 201011152355) Operating System = Linux version 2.6.37-generic running on amd64 Java; VM; Vendor = 1.6.0_22 Runtime = Java HotSpot(TM) 64-Bit Server VM 17.1-b03
It might be relevant that this is happening in a Rails project, ie the Projects navigator is mapping apps/models to Models in this case.
