org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) Caused by: java.lang.NullPointerException at org.eclipse.wst.common.project.facet.ui.internal.ConvertProjectToFacetedFormRunnable.run(ConvertProjectToFacetedFormRunnable.java:80) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Reproducible: Always Steps to Reproduce: 1. Launch Eclipse IDE (3.6 SDK) in a workspace 2. Create a faceted project (say myProj) 3. Close the project from the project explorer 4. Now switch to Project properties page of the closed project. Project properties -> Project Facets 5. Observe that 'Convert to faceted from...' link is still available for a faceted project 6. Click on that link. Observe that null exception is logged silently in the log file.
This is still happening in WTP 3.6. Triaging to 3.6.1
Created attachment 244677 [details] Proposed patch In this patch, the facets page is hidden is the project is not open.
thanks
Committed to master for WTP 3.6.1 and 3.7. http://git.eclipse.org/c/webtools-common/webtools.common.fproj.git/commit/?id=ed3ae7091c3ea10584f758dc6065c560f6804d41 In the next 3.6.1 and 3.7 build, the facets page will be hidden if the project is closed. Resolving
