Build: NetBeans IDE 8.0.1 (Build 201408251540) VM: Java HotSpot(TM) 64-Bit Server VM, 25.11-b03, Java(TM) SE Runtime Environment, 1.8.0_11-b12 OS: Windows 8 User Comments: javydreamercsw: Trying to refactor. ecerichter: Encapsulating fields. Cursor was on attribute name. I've hit "Enter". Cursor moved to selection box for getter. I've hit "Ctrl+Enter" in order to confirm the generation, without changing anything from defaults. GUEST: Encapsulating Fields GUEST: error during refactor GUEST: I now have this error everytime I try to encapsulate fields. It started after I updated the latest patch. ecerichter: Encapsulating field. I've just hint "Enter" couple of times, then realized that I really need to "Ctrl+Enter" - then the exception was thrown. ecerichter: Trying to encapsulate fields. Reproducible always, even on 201210210002. What I've typed: 1) Shift+Ctrl+E over variable name (to open "Encapsulate Fields" dialog). 2) Hit "Enter" over the name. It doesn't confirm the window (as it did in the past) 3) Hit "Ctrl+Enter" to confirme de window. Error is thrown. ecerichter: 1) Put cursor over "id" attribute. 2) Call refactory -> encapsulate fields 3) Ecapsulate fields window is shown 4) Press enter (cursor move to the checkbox) 5) Press Ctrl+Enter to confirm the window Exception happens. salaboy: Refactoring -> encapulating fields Stacktrace: java.lang.NullPointerException at org.netbeans.modules.refactoring.java.plugins.EncapsulateFieldRefactoringPlugin.getRelevantFiles(EncapsulateFieldRefactoringPlugin.java:459) at org.netbeans.modules.refactoring.java.plugins.EncapsulateFieldRefactoringPlugin.prepareEncapsulator(EncapsulateFieldRefactoringPlugin.java:423) at org.netbeans.modules.refactoring.java.plugins.EncapsulateFieldsPlugin.prepare(EncapsulateFieldsPlugin.java:198) at org.netbeans.modules.refactoring.api.AbstractRefactoring.pluginsPrepare2(AbstractRefactoring.java:437) at org.netbeans.modules.refactoring.api.AbstractRefactoring.pluginsPrepare(AbstractRefactoring.java:421) at org.netbeans.modules.refactoring.api.AbstractRefactoring.prepare(AbstractRefactoring.java:232)
