Description dwaszak 2008-01-18 10:44:50 UTC

When I try to find usages of a class, Netbeans showed message:

"Module JavaServer Faces Support threw java.lang.NullPointerException. Please report a bug against JavaServer Faces
Support module and attach your var/log/messages.log."


Content of messages.log file:

SEVERE [global]
java.lang.NullPointerException
	at org.netbeans.modules.web.jsf.refactoring.Occurrences.getAllOccurrences(Occurrences.java:442)
	at org.netbeans.modules.web.jsf.refactoring.JSFWhereUsedPlugin.prepare(JSFWhereUsedPlugin.java:114)

	at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:561)
	at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:986)


The error was repeatable (even if i tried to find usage of different class).

Project is a maven2 web application, created in Eclipse, and opened in NB.

Reassigning to web-jsf for evaluation

Comment 2 _ potingwu 2008-01-22 19:36:58 UTC

I cannot reproduce it on regular NetBeans projects. Please attach your 'Eclipse Maven2' web project for further evaluation.

Comment 3 _ potingwu 2008-01-22 19:52:43 UTC

Does the workaround in issue#116418 work for you? I.e., remove the namespace of your faces-config.xml file.

Comment 4 _ potingwu 2008-01-23 17:34:49 UTC

Still waiting for more information from the reporter to get further investigation.

Comment 5 dwaszak 2008-01-25 12:35:12 UTC

As far as I know this is not an JSF project. 

For sure it does not have faces-config.xml file. 

It is a webapp, built using freemarker templates. 

It is a commercial project (I'm only a consultant) hence I can not attach any sources. 

But I can provide you with most of configuration files - but I need to know which one you would like to see.

Comment 6 _ potingwu 2008-03-21 17:23:13 UTC

As discussed with Petr Pisl, the solution should follow xml specification. Which means that if there is an element
defining a namespace, then all subelements without a namespace has the same. Therefore, we will always use the namepsace
that appears in the <faces-config> for the comparison. I.e., the getQName() method has been restructured.
