The BO is used both on a form and a SFUserControl, using BOTranslations. During the form's initialization, a call is made eventually to the BusinessObjectTranslator.TranslateBusinessObjects method, which eventually calls the BusinessLayer.CopyEventHandlersFrom method.<br/><br/><div>For all the "standard" events, CopyEventHandlersFrom calls the GetValidInvocationList method to weed out any handlers that shouldn't be copied. However, the code which handles the Miscellaneous events doesn't do this. &nbsp;Instead, it just makes a direct copy of the destination BO's miscellaneous events to the sourceBO. &nbsp;<br/><br/><div>Therefore, CopyEventHandlersFrom leaves the sourceBO with duplicated events (sourceBO's original event + destBO's event). &nbsp;When the event is raised, a call is eventually made to the destBO's event handler, which promptly causes an exception.<br/><br/><div>(Just for comparison, when using a CFD, the routine BusinessLayer.PushEventsFrom is called, which handles this situation correctly)Mon, 16 Apr 2012 13:38:05 GMTKirk M Sherhart
