Bug 35265 NPE in classpath variables page
Reported: 2003-03-18 19:21:46 | Status: verified fixed

Build: I-20030317 I was switching back and forth between target platform and classpath variables preference pages, changing values on target platform page and seeing if changes are reflected on classpath variables page. At some point, I got the following null pointer: java.lang.NullPointerException at org.eclipse.jdt.internal.ui.wizards.buildpaths.CPVariableElementLabelProvider.ge tImage(CPVariableElementLabelProvider.java:55) at org.eclipse.jface.viewers.TableViewer.doUpdateItem(TableViewer.java:202) at org.eclipse.jface.viewers.StructuredViewer$UpdateItemSafeRunnable.run (StructuredViewer.java:119) at org.eclipse.core.internal.runtime.InternalPlatform.run (InternalPlatform.java:867) at org.eclipse.core.runtime.Platform.run(Platform.java:413) at org.eclipse.jface.viewers.StructuredViewer.updateItem (StructuredViewer.java:1271) at org.eclipse.jface.viewers.TableViewer.internalRefresh(TableViewer.java:454) at org.eclipse.jface.viewers.TableViewer.internalRefresh(TableViewer.java:431) at org.eclipse.jface.viewers.StructuredViewer$7.run(StructuredViewer.java:861) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection (StructuredViewer.java:801) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:859) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:821) at org.eclipse.jdt.internal.ui.wizards.dialogfields.ListDialogField.refresh (ListDialogField.java:739) at org.eclipse.jdt.internal.ui.wizards.buildpaths.VariableBlock.refresh (VariableBlock.java:406) at org.eclipse.jdt.internal.ui.preferences.ClasspathVariablesPreferencePage.setVisi ble(ClasspathVariablesPreferencePage.java:80) at org.eclipse.jface.preference.PreferenceDialog.showPage (PreferenceDialog.java:1064) at org.eclipse.jface.preference.PreferenceDialog$9.run (PreferenceDialog.java:496)
