Created attachment 195767 [details] Log I20110512-2000 After bug 336080, the deadlock is gone, but I get a few "Widget disposed" exceptions in the log when I close the DS editor quickly after save. Looks like a design flaw that ManagedForm#doRefresh() runs updates after the form has been disposed. I didn't find a way how ManagedForm could deal with this without API changes, so I guess implementers of IFormPart#refresh() need to check whether their widgets are disposed. Bug 316441 looks like a similar problem. One example (log has the rest): Caused by: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4277) at org.eclipse.swt.SWT.error(SWT.java:4192) at org.eclipse.swt.SWT.error(SWT.java:4163) at org.eclipse.swt.widgets.Widget.error(Widget.java:477) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:349) at org.eclipse.swt.widgets.Table.deselectAll(Table.java:1966) at org.eclipse.jface.viewers.TableViewer.doDeselectAll(TableViewer.java:277) at org.eclipse.jface.viewers.AbstractTableViewer.setSelectionToWidget(AbstractTableViewer.java:908) at org.eclipse.jface.viewers.StructuredViewer.setSelectionToWidget(StructuredViewer.java:1767) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1450) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1404) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:1506) at org.eclipse.jface.viewers.ColumnViewer.refresh(ColumnViewer.java:537) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:1465) at org.eclipse.pde.internal.ds.ui.editor.sections.DSPropertiesSection.refresh(DSPropertiesSection.java:175) at org.eclipse.ui.forms.ManagedForm.doRefresh(ManagedForm.java:206) at org.eclipse.ui.forms.ManagedForm.access$0(ManagedForm.java:201) at org.eclipse.ui.forms.ManagedForm$1.run(ManagedForm.java:195) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135)
