And I cose teh message window,and open my project on my disk,my IDE also message the same information. At last, I uninstall my IDE from my computer,and reinstall it. When I open my new-installed IDE,and open a project(BTW,my application is based on netBeans Platform,and my JDK is 5.0),the IDE also message me the same information.I really don't know why!Please help me!Thanks so much! 16 DEC 2005 Jason S.H.Chen
What types of projects do you have opened in the projects tab? This seems that (at least) one of them returns "null" from ProjectInformation.getDisplayName(). Do you have your own project type?
I open a Module Suite Project,it's Category is NetBeans Plug-in Modules,include Module Suite Project,Library Wrapper Module Project and Mudule Project. I create the project use netBeans 5.0 before,and I can open it before. Now I open every Module Suite Project,the same thing will occur.Please help me,thanks very much!
Need a log file, and preferably some sort of steps to reproduce, preferably in a dev build. I will patch OpenProjectList.ProjectByDisplayNameComparator to supply better diagnostics.
I found two possible bugs in apisupport that could cause this: - somehow corrupt project.xml (perhaps due to use of obsolete buggy JDK?) - OpenIDE-Module-Localizing-Bundle defined in manifest.mf, and that .properties present, but (for some reason) without OpenIDE-Module-Name defined in it I will try to fix both for a future release. Cannot know which was the problem for reporter.
Now I have uninstalled the netBeans 5.0 Beta 2,and installed netBeans 5.0 Beta 1 that I have downloaded before.Now I can open the same projects that opened by netBeans 5.0 Beta 2 occurring errors.Everything is ok!I'm sorry that I can't provide the log file,because I have Uninstalled netBeans 5.0 Beta 2.
Well fixing what I can, maybe it will help the next person: committed * Up-To-Date 1.133 apisupport/project/src/org/netbeans/modules/apisupport/project/NbModuleProject.java committed * Up-To-Date 1.47 projects/projectui/src/org/netbeans/modules/project/ui/OpenProjectList.java
Just improving summary.
