This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
1) Work on a large file like the OTA schema. Keep expanding columns, editing etc., 2) Delete the file throws the exception below: 3) This is sometimes reproducible in schema but a related bug is more reproducible from BPEL. The first four lines of the stack trace is also seen while running validation from BPEL. So once this is fixed in xam, the other bpel validation bug can also be fixed. java.lang.NullPointerException at org.openide.util.lookup.InstanceContent$SimpleItem.<init>(InstanceContent.java:150) at org.openide.util.lookup.SimpleLookup.<init>(SimpleLookup.java:47) at org.openide.util.lookup.Lookups.fixed(Lookups.java:75) at org.netbeans.modules.xml.retriever.catalog.Utilities$1.getLookup(Utilities.java:595) at org.openide.util.lookup.SimpleProxyLookup.checkLookup(SimpleProxyLookup.java:55) at org.openide.util.lookup.SimpleProxyLookup.lookup(SimpleProxyLookup.java:116) at org.netbeans.modules.xml.xam.dom.AbstractDocumentModel.needsSync(AbstractDocumentModel.java:89) at org.netbeans.modules.xml.xam.AbstractModel.prepareSync(AbstractModel.java:208) at org.netbeans.modules.xml.xam.AbstractModel.runAutoSync(AbstractModel.java:496) at org.netbeans.modules.xml.xam.AbstractModelFactory$1.run(AbstractModelFactory.java:94) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:499) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:932)

Praveen, please note that now a modelsource lookup could return null for File or FileObject in which case it means the source file has been delete or has io issue since the model source was created. So, (validation) background process needs to check for this condition properly.
Additional changes to xsd based validators that might be run in the background. /cvs/xml/schema/api/src/org/netbeans/modules/xml/schema/model/validation/Attic/SchemaXsdBasedValidator.java,v <-- SchemaXsdBasedValidator.java new revision: 1.1.2.6; previous revision: 1.1.2.5 cvs/xml/xam/src/org/netbeans/modules/xml/xam/spi/Attic/XsdBasedValidator.java,v <-- XsdBasedValidator.java new revision: 1.1.2.9; previous revision: 1.1.2.8
