Bug 116706 Bad Class Cast in IDEReportEditor.java
So I'm trying to open a report with BIRT/Eclipse API using the BIRT 2.0 nightly build code (as of 11/16/2005). the file IDEReportEditor.java method private IFile getFile( IEditorInput input ) { return ( (ReportFileEditorInput) input ).getFile( ); } However, input can be ReportEditorInput which is also an IEditorInput (to support reports found outside projects and workspaces) which doesn't even have a getFile() method on it. This causes a deeply nested exception that causes the report desinger to not be able to show a report that might be physically located outside a workspace.

		public ISelection getSelection( )
		{
			IEditorPart activeEditor = ( (FormEditor) getMultiPageEditor( ) ).getActivePageInstance( );
			
			if ( activeEditor != null )
			{
				ISelectionProvider selectionProvider = activeEditor.getSite( )
						.getSelectionProvider( );
				if ( selectionProvider != null )
					return selectionProvider.getSelection( );
			}
			return globalSelection;
		}
		/*

		public void setSelection( ISelection selection )
