Build Identifier: 3.6.2.v20110128-0100 We have a org.eclipse.gmf.runtime.draw2d.ui.figures.WrappingLabel which uses a TextFlow. This label is updated from a non-UI Thread via Display.asyncExec(). Normally this works fine, i.e. setting the text makes the label invalid and forces correct calculation of the text flow and revalidation. However, there are situations where the Thumbnail (visible in an Outline) update code calls paint() and forces the TextFlow to paint itself even though the label/flow is currently invalid. Thus we can run into a StringIndexOutOfBoundsException because the new text has been set, but the flow has not be recalculated yet. org.eclipse.swt.SWTException: Failed to execute runnable

TextFlowEx (from gmf) computes the TextFragmentBox and passes it on TextFlow. There are some differences in that calculation between the code of TextFlow and TextFlowEx (I picked this up using online code grep). Maybe the problem is in TextFlowEx?
