When I try to add a query column in the Papyrus Table Editor, I get the following exception : java.lang.IllegalStateException: Cannot modify resource set without a write transaction at org.eclipse.emf.transaction.impl.TransactionChangeRecorder.assertWriting(TransactionChangeRecorder.java:348) at org.eclipse.emf.transaction.impl.TransactionChangeRecorder.appendNotification(TransactionChangeRecorder.java:302) at org.eclipse.emf.transaction.impl.TransactionChangeRecorder.processObjectNotification(TransactionChangeRecorder.java:284) at org.eclipse.emf.transaction.impl.TransactionChangeRecorder.notifyChanged(TransactionChangeRecorder.java:240) at org.eclipse.emf.common.notify.impl.BasicNotifierImpl.eNotify(BasicNotifierImpl.java:380) at org.eclipse.emf.ecore.util.EcoreEList.dispatchNotification(EcoreEList.java:255) at org.eclipse.emf.common.notify.impl.NotifyingListImpl.addUnique(NotifyingListImpl.java:310) at org.eclipse.emf.common.util.AbstractEList.add(AbstractEList.java:307) at org.eclipse.emf.facet.widgets.nattable.TableLabelProvider.getColumnText(TableLabelProvider.java:176) at org.eclipse.emf.facet.widgets.nattable.painter.CustomizedCellPainter.convertDataType(CustomizedCellPainter.java:80) at org.eclipse.emf.facet.widgets.nattable.painter.CustomizedCellPainter.paintCell(CustomizedCellPainter.java:139) at net.sourceforge.nattable.painter.layer.CellLayerPainter.paintCell(CellLayerPainter.java:60) at net.sourceforge.nattable.selection.SelectionLayerPainter.paintCell(SelectionLayerPainter.java:123) at net.sourceforge.nattable.painter.layer.CellLayerPainter.paintLayer(CellLayerPainter.java:33) at net.sourceforge.nattable.painter.layer.GridLineCellLayerPainter.paintLayer(GridLineCellLayerPainter.java:16) at net.sourceforge.nattable.selection.SelectionLayerPainter.paintLayer(SelectionLayerPainter.java:34) at net.sourceforge.nattable.layer.CompositeLayer$CompositeLayerPainter.paintLayer(CompositeLayer.java:884) at net.sourceforge.nattable.NatTable$NatLayerPainter.paintLayer(NatTable.java:651) at net.sourceforge.nattable.NatTable.paintNatTable(NatTable.java:292) at net.sourceforge.nattable.NatTable.paintControl(NatTable.java:288) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:229) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1053) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1077) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1062) at org.eclipse.swt.widgets.Composite.WM_PAINT(Composite.java:1564) at org.eclipse.swt.widgets.Control.windowProc(Control.java:4564) at org.eclipse.swt.widgets.Canvas.windowProc(Canvas.java:341) at org.eclipse.swt.widgets.Display.windowProc(Display.java:4946) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2523) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3713) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2697) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2661) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2495) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386) Error while painting table: Cannot modify resource set without a write transaction
Created attachment 190258 [details] Patch Bug 337398 Hi, I've changed the query evaluation mechanism in the Table in order to fix this exception. I've also removed the adapter which was added to the eObject because : - It was not the responsibility of the concerned method to manage it. - It was not the right behavior, the result of a query is not only modified if the eObject change, but also if the resource containing it changes. (a) I, Nicolas Guyomar, wrote 100% of the code I've provided. (b) I have the right to contribute the code to Eclipse. (c) I contribute the content under the EPL. Regards, Nicolas Guyomar
