Probably problem in j2ee/earproject, reassigning there.

I have added some debug code which will warn users when the situation happen and
ask them to add more details about the situation to this issue.

Checking in

 <--  LogicalViewChildren.java
new revision: 1.7; previous revision: 1.6
done

probably fixed?!? - noone complained about this even I added an informational
exception with link to this issue before more than month. I am closing the issue
as fixed, please reopen when you encounter it along with some details about the
situation when it happened.

I am using NetBeans 5.5 Beta and an error dialog appear:
java.lang.IllegalStateException:
FileOwnerQuery.getOwner(MasterFileObject@833bf3[D:/J2EEFCS/FCServerApplication])
returned null. Please report this with the situation description to issue #62823
(http://www.netbeans.org/issues/show_bug.cgi?id=62823).

sorry for my very bad english

I've got this as well trying to reproduce 81017. This may happen when the
project was deleted but someone still listening on project.xml (which could be
e.g. newly created?). Either we should get away of the warning (IAE) or fix it
otherways.

Not for 5.5. Needs more investigation, and seems to be harmless and we are few
hours before high-resistance.

J2EE team support ends, thus returning the issue back.

this exception occurs when working on project, which files has been deleted
manually.

its in netbeans-5_5_1-beta-bin-200702211400-21_Feb_2007_1400 build.

more about cause of error :

Got a window message form IDE telling me to update this issue 62832 with the working situation as hit this
NPE at creating a new EE project that had been deleted before.

Environment: 
NB 6.0 200707050000 & GF v2 b54 & jdk 1.6u1 on windows XP.

I've created a new EE project with IDE using File "New Project", Samples-> Enterprise->Interceptor Stateless
please see : 109006 about the different steps I've done to break the ear reference for my app-client module.
"Remove" action from Java EE Modules/app-client and "Add Java EE Module" again for this app-client

as I wanted to reproduce again to copy/paste the build.xml (run) output, I've deleted the EE project
and got the NPE window, deleted the dep projects, and recreate again.

I will attach the IDE-Log file messages.log

nouar (located in France, helping in testing GF serverplugin).

Created attachment 44764 [details]
IDE-log file processed using dos2unix

adding myself in cc. The exception is harmless as said by the IDE-Windows 6.0: delete is ok, recreate is ok.

we can keep RANDOM keyword, at create after the delete (second time), can see NPE + many other exceptions IOBE: last
shown in IDE-window is:

Deployment descriptor (application.xml) is not compulsory for JAVA EE 5.
If it's *really* needed, set force param to true.



reproduced on WinXP, with jdk1.5.0_09, nb6.0 build: 20071002041043
steps to reproduce:

 1. create new Enterprise Module (EnterpriseApplication2)
   in the new project wizard on the second step - "Name and Location" uncheck "Create Ejb Module" and "Create Web
Application Module"
 2. close project
 3. delete project directory 
 4.  repeat step 1 with the same name (EnterpriseApplication2) and see exception...
  

Got the same exception with the similar steps to reproduce (just one correction on the point 1 - don't change any
default settings i.e.:

 1. create new Enterprise Module (EnterpriseApplication2)
 2. close project
 3. delete project directory (EnterpriseApplication2)
 4.  repeat step 1 with the same name (EnterpriseApplication2) and see exception...

)

Just closed a project and removed it from the file system. When went back to NetBeans IDE Dev (Build 200802100004) got
the exception. The message told me to update the issue so here I am. See the attachment for more information.
