release fix
I have a similar problem, but with Indigo (Build id: 20110916-0149), while it was working correctly on Helios. I have a tree containing items with images. When I remove some elements of this tree and then I call refresh on this tree (while the tree is visible), I have a crash with the following error: !ENTRY org.eclipse.ui 4 0 2011-10-26 18:13:55.340 !MESSAGE Unhandled event loop exception !STACK 0 org.eclipse.swt.SWTException: Graphic is disposed at org.eclipse.swt.SWT.error(SWT.java:4282) at org.eclipse.swt.SWT.error(SWT.java:4197) at org.eclipse.swt.SWT.error(SWT.java:4168) at org.eclipse.swt.graphics.Image.getImageData(Image.java:1209) at org.eclipse.swt.internal.ImageList.set(ImageList.java:405) at org.eclipse.swt.internal.ImageList.add(ImageList.java:70) at org.eclipse.swt.widgets.Tree.imageIndex(Tree.java:3639) at org.eclipse.swt.widgets.Tree.wmNotifyChild(Tree.java:7347) at org.eclipse.swt.widgets.Control.wmNotify(Control.java:5534) at org.eclipse.swt.widgets.Composite.wmNotify(Composite.java:1896) at org.eclipse.swt.widgets.Control.WM_NOTIFY(Control.java:5086) at org.eclipse.swt.widgets.Control.windowProc(Control.java:4584) at org.eclipse.swt.widgets.Display.windowProc(Display.java:4985) at org.eclipse.swt.internal.win32.OS.CallWindowProcW(Native Method) at org.eclipse.swt.internal.win32.OS.CallWindowProc(OS.java:2425) at org.eclipse.swt.widgets.Tree.callWindowProc(Tree.java:1533) at org.eclipse.swt.widgets.Control.windowProc(Control.java:4623) at org.eclipse.swt.widgets.Tree.windowProc(Tree.java:5937) at org.eclipse.swt.widgets.Display.windowProc(Display.java:4972) at org.eclipse.swt.internal.win32.OS.UpdateWindow(Native Method) at org.eclipse.swt.widgets.TreeItem.setExpanded(TreeItem.java:1262) at org.eclipse.jface.viewers.TreeViewer.setExpanded(TreeViewer.java:332) at org.eclipse.jface.viewers.AbstractTreeViewer.updateChildren(AbstractTreeViewer.java:2767) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefreshStruct(AbstractTreeViewer.java:1908) at org.eclipse.jface.viewers.TreeViewer.internalRefreshStruct(TreeViewer.java:721) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh(AbstractTreeViewer.java:1883) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh(AbstractTreeViewer.java:1840) at org.eclipse.jface.viewers.AbstractTreeViewer.internalRefresh(AbstractTreeViewer.java:1826) at org.eclipse.jface.viewers.StructuredViewer$7.run(StructuredViewer.java:1508) 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.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 myApp.StructureMergeViewer.refresh(StructureMergeViewer.java:226)
