OS: Windows 7 x64, Build 7000 Reproduced on: Netbeans 6.5, Netbeans 7.0M1 Information from "about" screen: Product Version: NetBeans IDE Dev (Build 200812180001) Java: 1.6.0_11; Java HotSpot(TM) 64-Bit Server VM 11.0-b16 System: Windows Vista version 6.1 running on amd64; Cp1252; en_US (nb) Userdir: C:\Users\mpdelbuono\.netbeans\7.0m1 Reproducibility: Always Problem description: When loading a Java project which is unable to find libraries, the "Resolve Reference Problems" dialog is used to resolve the issue. Unfortunately, on Windows 7, this dialog is inoperative. Upon opening the "Resolve Reference Problems" dialog, the component which would normally display the libraries list is missing. As a result, reference problems cannot be resolved because the appropriate libraries cannot be identified (or created, if necessary). Possible workarounds: None known at the moment, however I am not familiar with the format of the internal project files. It may be possible to manually edit the project files to resolve the reference problems without the use of this dialog. Note points: This may be an issue caused by Windows 7 (or perhaps a problem with the JRE on Windows 7) and not an issue with Netbeans. I can confirm that this issue did not exist for me in the past on Windows Vista. As of yet I am unable to isolate whether the culprit is Windows 7, the JRE, or Netbeans itself.
I'm lowering priority since Windows 7 is not supported platform at this time.
I was just able to duplicate this on Kubuntu 8.10 It appears that the issue may actually be caused by one of my projects. I normally have 5 projects open (they are all related). However, closing all of them except one allows me to resolve the reference problems as normal. This implies that one of the other open projects was causing the problem to me. The one I left open only has one reference problems; the others have several. I will continue testing to see if that may be the trigger.
I was able to isolate the problem to a single project. Unfortunately, right clicking and going to "properties" and deleting all of the projects listed did not resolve the problem. I also cannot add libraries from the properties dialog. When I choose "Add Library," no libraries are listed. The project in question is an old project which may have originally been created in an earlier version of Netbeans. I am going to try recreating the project and moving all of the files over to see if this resolves the issue.
After recreating the project in another folder, moving all of the source and library files to the new project, then overwriting the old project (i.e., overwriting the nbproject folder with the newly created version), it appears the problem has been fixed. I would blame this to project corruption when upgrading between netbeans versions, probably. This is an old project, so it wouldn't surprise me.
Thanks for info. Closing the issue as it was probably smehow broken project from previous NetBeans releases.
