Since yesterday the m2e context menus in eclipse pacakge explorer stopped working. Neither of the above mentioned menu items show the dialogs they used to show. I remember having updated Eclipse recently but am not sure which plugins have been updated. Will let you know when I have time to get into this. -- Error Details -- Date: Tue Feb 07 10:09:05 CET 2012 Message: Unhandled event loop exception Severity: Error Product: Eclipse 1.4.1.20110909-0613

I have not seen this problem and have not heard other reports about it. Feel free to reopen if this still happens to you.
I see this as well, major PITA as it prevents m2e updating a project's configuration. org.eclipse.core.runtime.AssertionFailedException: null argument: at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:85) at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:73) at org.eclipse.jface.viewers.StructuredViewer.assertElementsNotNull(StructuredViewer.java:599) at org.eclipse.jface.viewers.StructuredViewer.getRawChildren(StructuredViewer.java:1011) at org.eclipse.jface.viewers.ColumnViewer.getRawChildren(ColumnViewer.java:703) at org.eclipse.jface.viewers.AbstractTreeViewer.getRawChildren(AbstractTreeViewer.java:1336) at org.eclipse.jface.viewers.TreeViewer.getRawChildren(TreeViewer.java:391) at org.eclipse.jface.viewers.StructuredViewer.getFilteredChildren(StructuredViewer.java:917) at org.eclipse.jface.viewers.AbstractTreeViewer.getSortedChildren(AbstractTreeViewer.java:605) at org.eclipse.jface.viewers.AbstractTreeViewer$1.run(AbstractTreeViewer.java:805) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:70) at org.eclipse.jface.viewers.AbstractTreeViewer.createChildren(AbstractTreeViewer.java:782) at org.eclipse.jface.viewers.TreeViewer.createChildren(TreeViewer.java:644) at org.eclipse.jface.viewers.AbstractTreeViewer.createChildren(AbstractTreeViewer.java:753) at org.eclipse.jface.viewers.AbstractTreeViewer.internalInitializeTree(AbstractTreeViewer.java:1533) at org.eclipse.jface.viewers.TreeViewer.internalInitializeTree(TreeViewer.java:833) at org.eclipse.jface.viewers.AbstractTreeViewer$5.run(AbstractTreeViewer.java:1517) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1443) at org.eclipse.jface.viewers.TreeViewer.preservingSelection(TreeViewer.java:403) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1404) at org.eclipse.jface.viewers.CheckboxTreeViewer.preservingSelection(CheckboxTreeViewer.java:416) at org.eclipse.jface.viewers.AbstractTreeViewer.inputChanged(AbstractTreeViewer.java:1510) at org.eclipse.jface.viewers.ContentViewer.setInput(ContentViewer.java:280) at org.eclipse.jface.viewers.StructuredViewer.setInput(StructuredViewer.java:1690) at org.eclipse.m2e.core.ui.internal.dialogs.UpdateDepenciesDialog.createDialogArea(UpdateDepenciesDialog.java:193) at org.eclipse.jface.dialogs.TitleAreaDialog.createContents(TitleAreaDialog.java:155) at org.eclipse.jface.window.Window.create(Window.java:431) at org.eclipse.jface.dialogs.Dialog.create(Dialog.java:1089) at org.eclipse.jface.window.Window.open(Window.java:790) at org.eclipse.m2e.core.ui.internal.actions.UpdateDependenciesAction.run(UpdateDependenciesAction.java:32) at org.eclipse.ui.internal.PluginAction.runWithEvent(PluginAction.java:251) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:584) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:501) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:411) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4128) … etc. I have the scala-ide plugin installed as well.
@Jed what m2e version are you using? Bug 369932 looks very similar to this one and it has been fixed in 1.1RC1.
