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.
see http://netbeans.org/bugzilla/show_bug.cgi?id=221102, which was filed against ide/code, but should be against web/HTML5 Project java.lang.NullPointerException at org.netbeans.modules.web.clientproject.ClassPathProviderImpl$PathImpl.getRoots(ClassPathProviderImpl.java:103) at org.netbeans.api.java.classpath.ClassPath.entries(ClassPath.java:358) at org.netbeans.api.java.classpath.ClassPath.toString(ClassPath.java:689) at org.netbeans.api.java.classpath.ClassPath.toString(ClassPath.java:725) at org.netbeans.modules.parsing.impl.indexing.LogContext.addPaths(LogContext.java:438) at org.netbeans.modules.parsing.impl.indexing.PathRegistry.scheduleFirer(PathRegistry.java:822) (org-netbeans-modules-web-clientproject.jar)
Another example is issue http://netbeans.org/bugzilla/show_bug.cgi?id=221449 - should have better component too.
I think the problem is somewhere else ... the current mapping says : org-netbeans-modules-web-clientproject.jar web HTML5 Project and that's obviously wrong ... just because there is no HTML5 Project component ... I think we need to change this mapping significantly, at least it needs to reflect actual names of products/components in BZ ... see issue 211224 I fixed current mapping for web product
